Determination of carbon disulphide in air as xanthogenate by ion chromatography and capillary electrophoresis

A simple and sensitive method is presented for the measurement of carbon disulphide in air without interference from other gaseous sulphides. The procedure is based on the collection of CS2 in an ethanolic solution of KOH, where it is converted to potassium ethyl xanthogenate (PEX). The latter is determined by high-performance ion chromatography (HPIC) and/or capillary zone electrophoresis (CZE). Laboratory and field determination of detection limit, reproducibility and linearity, and specific advantages over other gas chromatographic and wet chemical methods, are discussed. Quantitative measurements of CS2 in air can be performed after sampling for 1 h with limits of detection as low as 15 ppb by HPIC and ca 0.1 ppm by CZE.

Sampling and determination of carbon disulphide in air by gas chromatography with electron-capture detection

In this paper we report the determination of carbon disulphide by GC with electron-capture detection after its collection from air using different absorption tubes

Determination of carbon disulphide through xanthate by radiorelease method employing radiochloramine-T

Carbon disulphide can be determined at ppm level by converting it into xanthate and then oxidizing it by radiochloramine-T in acid medium. Interference of sulphide, sulphite and nitrite can be eliminated by extracting CS2 from the mixture into carbon tetrachloride and stripping it into aqueous medium as xanthate by the addition of alcoholic KOH to the organic layer.

Determination of carbon disulphide in water

It could be demonstrated that the determination of CS2 in water and waste water is generally not affected by solids in lower quantities. An alkalization is recommended in the presence of hydrogen sulphide.

Quantitative analysis of disulfiram and its metabolites in human blood by gas-liquid chromatography

A simple method is described that permits the direct quantitative determination of carbon disulphide, free diethyldithiocarbamate and disulphides derived from disulfiram in 1 ml of a patient's blood. It is based on a gas chromatographic determination of carbon disulphide produced from diethyldithiocarbamate and disulfiram using the head-space technique and a flame-photometric detector. The method is compared with a recently described spectrophotometric method.

Determination of carbon disulphide by chloramine-T

Carbon disulphide, on treatment with alcoholic potash, can readily be oxidised quantitatively by chloramine-T, converting all the sulphur to sulphuric acid. Fourteen equivalents of the oxidant are consumed for every mole of carbon disulphide. Since excess of chloramine-T may be determined iodimetrically, this reaction may be used for the determination of carbon disulphide. It may also be applied to the determination of xanthates.
