With a view to study the leaching potential and consequently surface and ground water contamination, the adsorption of dimethoate on five soils of different characteristics has been carried out by using a batch equilibrium technique. A spectrophotometric methodology based on the reaction of thioglycolic acid, formed from microwave assisted alkaline hydrolysis of dimethoate, with carbon disulfid...

A flow-electrolytic cell that consists of a bare gold wire or of different thiol-compound-modified gold electrodes (such as 2,4-thiazolidinedione, 2-mercapto-5-thiazoline, 2-mercaptothiazoline, l-cysteine, thioglycolic acid) was designed to be used in a voltammetric detector to identify l-selenomethionine and Se-methylseleno-l-cysteine using high-performance liquid chromatography. Both l-seleno...

Thiol functionalization of psyllium was carried out to enhance its mucoadhesive potential. Thiolation of psyllium was achieved by esterification with thioglycolic acid. Thiolation was observed to change the surface morphology of psyllium from fibrous to granular and result in a slight increase in the crystallinity and swelling. Thiolated psyllium was found to contain 3.282 m moles of thiol grou...

In the study of many types of biological material it has become of increasing importance to determine accurately extremely small amounts of iron. Since color reactions are, as a rule, very sensitive, calorimetric procedures are particularly useful in the microanalytical field, and several calorimetric methods have appeared in the literature on iron determination. Although the extremely sensitiv...

Introduction: Corrosion inhibitor (CI) is injected as carbon steel pipe corrosion protection with sulfur-containing substances in the product. One type of them thioglycolic acid (TGA). Besides having benefits maintaining integrity, TGA can be decomposed to HS (hydrogen sulfide) due changes ambient temperature during storage, such direct sunlight exposure on field. This irritant gas pose a risk ...
