This work with the measurement of interfacial area obtained by mixing of two liquid phases. For that purpose, the chemical method has been chosen, but the extent of the reaction has been measured by thermal analysis. The values of interfacial area have then been related to operating conditions and physical properties of the phases.

The measurement of interfacial area and surface‐renewal rate in a bubble‐cap plate

AbstractIt is shown how interfacial area and surface‐renewal rate in a bubble‐cap plate can be determined from absorption‐rate measurements of CO2 into carbonate‐bicarbonate solutions in which the pseudo‐first‐order rate constant is varied by catalysis. A method of measuring the rate of constants of the experimental solutions is also described.

Interfacial area in liquid‐liquid mixing

AbstractIn predicting interfacial area in liquid‐liquid systems there are several published reports which give different results. Differences in methods of measurement of interfacial area and impeller design and location account for some of these discrepancies.For one pair of liquids, 40 parts by volume of ethylhexanol and 60 parts water, it was found that over wide ranges of impeller size to tank size ratio (0.27 to 0.67) that equal power per unit volume gave equal interfacial area per unit volume.

Liver disease is one of the common health problems as it is exposed to many kinds of therapeutic agents and xenobiotics. The present investigation was aimed at examining the possible antioxidant and protective role of Ecbolium viride (Forssk.) Alston against paracetamol-induced hepatotoxicity.The plant extract (100, 200 and 400 mg/kg, p.o.) showed a remarkable hepatoprotective activity against paracetamol-induced hepatotoxicity as judged from the serum marker enzymes in rats. Paracetamol induced a significant rise in aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total bilirubin. Treatment of rats with different doses of plant extract (100, 200 and 400 mg/kg) significantly (P < 0.001) altered serum marker enzymes levels to near normal against paracetamol treated rats. The activity of the extract at dose of 400 mg/kg was approximately comparable to the standard drug, silymarin (25 mg/kg, p.o.).Antioxidant activity of the extract was evaluated by using diphenyl picryl hydrazyl (DPPH) radical scavenging, Nitric oxide (NO) radical scavenging, Superoxide radical scavenging, Hydrogen peroxide (H2O2) scavenging, Hydroxy radical scavenging and Lipid peroxidation inhibitory methods. Histopathological changes of liver samples were compared with respective control.The present study revealed that ethanolic extract of E. viride (Forssk.) Alston roots has significant hepatoprotective activity against paracetamol-induced hepatotoxicity in rats and antioxidant potential.
