The microdetermination of mercuric mercury

Abstract A new titrimetric method for the microdetermination of mercuric mercury is described. The proposed method is based on the fact that aqueous l -ascorbic acid solution reduces mercuric mercury to mercurous mercury; itself being oxidized to dehydro- l -ascorbic acid. The mechanism of the reaction is discussed. The proposed method is simple, rapid, and sufficiently accurate to determine concentrations as low as 100 μg of mercuric mercury. The experimental error does not exceed ±2%. The method was also used for the determination of corrosive sublimate in such biological fluids as urine or milk with an error not exceeding ±10%.

Nephrotic Syndrome With Use of Ammoniated Mercury

IT IS well known that mercury can affect renal function. Organic mercurials can produce diuresis, and organic or inorganic mercurial compounds taken in therapeutic or excessive dosages may cause tubular necrosis, proteinuria, or the nephrotic syndrome. This syndrome has been associated with mercurial diuretics 1-4 ; mercurous chloride in calomel-containing powders 5,6 ; the mercury salt of fulminic acid 7 ; vapor from paint additives containing mercuric chloride, mercury, and phenol mercury 1 ; the protiodide of mercury 8 ; and vapor in the mercury industry containing mercury, mercurous chloride, mercuric chloride, mercuric oxide, and phenyl mercury acetate. 9 Ammoniated mercury, an inorganic compound whose formula is HgNH 2 CL, has been implicated in the production of proteinuria 10-12 and the nephrotic syndrome 1,13 14 (Table 1). Following is a report of a case of nephrotic syndrome associated with use of ammoniated mercury. Report of a Case A 24-year-old white man, a bank cashier from

The precipitation behavior of group IIB cations with oxyanions of selenium and tellurium

The compositions and aqueous solubilities at room temperature of the tellurites, tellurates, selenites and selenates of zinc, cadmium and mercury have been investigated. The techniques employed include pH and indicator-electrode titration and quantitative chemical analysis of filtrates. Substantial solubility was found for the tellurates and selenites of zinc and cadmium. Zinc, cadmium and mercuric mercury are all precipitated as the orthotellurates, M 2H 2TeO 6. The selenates of mercury are sparingly soluble and basic in nature; zinc and cadmium selenates are readily soluble. The tellurites of zinc, cadmium and mercury contain excess TeO 2 when precipitated from acid solutions.

Studies in the Two Phase System: Sodium Formate-Pyridine. VII. Extraction of Mercury

Abstract The distribution of mercuric mercury in the two phase system sodium formate-pyridine is studied. Almost quantitative extraction of mercury into pyridine is obtained from sodium formate (4 m) at a pH range of 7–7.5 with 5 ml. of pyridine and the extracted mercury is determined volumetrically using diphenylcarbazone as an internal indicator.

Histochemical demonstration of mercury in renal cells

A GREAT deal of effort has been expended, especially during the last decade, toward elucidation of the site and mechanism of action of mercurial diuretics. As a result of the contributions of many investigators,. several concepts have developed and are generally held. Histochemical studies dealing with renal protein-bound sulfhydryl groupsV and stopflow proceduresV indicate that the site of action is the proximal tubule. That the loop of Henle and collecting duct may participate cannot :be ruled out and, indeed, is actually implicated in the sulfhydryl stu’dies and also by the fact the mercurials interfere with potassium transport. Studies dealing with mechanism of action have centered around two focal points. The first involves the nature of the renal receptor and the second is concerned with the chemical nature of the reaction with receptor. A two-point receptor involving a sulfhydryl group has been suggested by Pitts et aZ.5 and by Mudge and Weiner6 but these investigators offer opposing views concerning the form of mercury which reacts with receptor. The dormer workers believe that mercury attaches by one valence to a point on the receptor. The second point of the receptor reacts with the organic fragment attached to the second valence of mercuric mercury; the latter have proposed that release of free mercuric io,n by fracture of a carbon-mercury bond, and subsequent attachment of divalent mercury to the double receptor are necessary for inhibition of sodium reabsorption. This conclusion is well-supported by their demonstrations that inorganic mercury attached to a suitable carrier seems to be more active than any organic compound, that acidotiis, which potentiates mercurial diuresis, speeds fracture of caribon-mercury bonds in vitro, and that stable mercury compounds are not diuretic. The work described Bin this report is an outigrowth of aI1 the valuable,

Application of colorimetric end-point to iodate : Procedures in presence of mercuric mercury

In the present investigations colorimetric titrations of arsenic(III), hydrazinc, thiosulphate and thiocyanate have been carried out by iodate procedures in the presence of mercuric ions. A Hilger Spekker absorptiometer unit (H 760) with a blue filter having a maximum transmission in the range of 450–500 mμ was employed for the titrations. Two end-points corresponding, respectively, to the reduction of iodate to iodide and the oxidation of the liberated iodide to iodine monochloride were obtained in HCl medium, the quantitative reduction of iodate to iodide being facilitated by the presence of mercuric ions. A study of the effect of the variation of acidity and dilution of the solution was carried out for both the end-points. As little as 5 mg of the reductants, could be determined with a precision of about 97% to 98%.

The use of naphthalene derivatives in inorganic analysis : The nitronaphthylamines as new reagents for mercuric mercury and ceric cerium

The use of 4-nitro-1-naphthylamme as a spot test for mercuric mercury and 1-nitro-2-naph-thylamine as a specific spot test for ceric cerium have been observed In each case, the reactions appear to be suitable for general qualitative inorganic analysis The ceric cerium test was specific whereas in the case of mercuric mercury. Ce +4 was the only on of 51 tested which interfered.

Application of amperometric dead stop end point to iodate procedures in presence of mercuric mercury

A general application of the amperometric Dead Stop end point to direct and indirect determinations with potassium iodate in presence of mercuric mercury has been indicated. Arsenious oxide and hydrazine sulphate may be used as direct primary standards and thiosulphate, thiocyanate, and thiourea are determined by excess iodate and backtitration with either of these standard reagents.

Action of Complexes of the Zinc Group Metals on the Tail Protein of Bacteriophage T 2 r +

A SPECIFIC reaction has been found between complexes of the zinc group metals and the bacterial virus, T 2 r +. Zinc ions (M/100) do not inactivate T 2 r +, but if a variety of metal-complexing agents are added to a solution containing zinc nitrate and T 2 r +, the virus is rapidly and irreversibly inactivated. Identical reactions occur with cadmium ions. Mercuric mercury inactivates T 2 as the free ion as well as when present as a complex ion. Cyanide complexes of all three metals and iodide complexes of cadmium and mercuric mercury inactivate the virus. Inactivation also occurs when a number of amino-acids (such as M/100 glycine or glutamic acid) and pure proteins (such as trypsin or chymotrypsin at 2 mgm./ml.) are used as metal-complexing agents. Versene complexes of zinc, cadmium or mercuric mercury do not affect the virus.

5-Methyl-7-nitroso-8-hydroxyquinoline and its sensitivity and selectivity towards certain metallic ions

5-Methyl-7-nitroso-8-hydroxyquinoline (5-methyl-7-nitroso-oxine), hitherto undescribed, has been prepared and tested for its sensitivity and selectivity towards various metallic ions at differing pH's. The metals tested include cadmium, ferrous and ferric iron, mercurous and mercuric mercury, lead, nickel, cobalt, thallous thallium, cerous and cerie cerium, copper, chromium, aluminium, zinc, magnesium, vanadium (as vanadate) and gallium. This reagent is comparatively “unsclective” in that it chelates with all the above metals under the conditions employed, and therefore closely follows the behaviour of the parent compound, 8-hydroxyquinoline (oxine). Its average sensitivity is somewhat greater than that of the parent compound, and it shows its greatest sensitivity with. divalent mercury.

1. A general method is presented for the determination of 1–2 mg mercuric mercury, in the absence of complexing agents, in 20 ml solution, with an error of 0–3 %. The solution may contain: Ca, Ba, Mg, Zn, Mn, Ni, Co or Cd as nitrate of sulphate in a concentration of 0.2 M. The concentration of Pb should be <0.1 M and that of Al, Cr or Fe ⩽0.05M. 2. A special method is presented for the determination of mercury (1–2 mg Hg in 20 ml) in the presence of large excesses of bismuth (≷98%) by using ethylendiammetetraacetate. Error 0–3 %. 3. A method is presented for the determination of mercury in excesses of copper in an acetic acid solution which contains ethylendiaminetetraacetate. 4. A special method is presented which permits the determination of 1–2 mg mercury in 30 ml solution which contains large excesses of copper (up to 98% or more). The titration is carried out in an alkaline solution of trisodiumcitrate. The titration proceeds rapidly. Error 0–2%.
