Abstract  

A rapid and selective method for the extraction of Ag/I/ with 2-mercaptobenzothiazole/2-HMBT/ into chloroform has been developed. The effect of various parameters on the extraction coefficient of Ag/I/ such as pH, time of equilibration, solvents, anion interferences, cation interference and stoichiometry of the metal to reagent have been established.

Abstract  

The extraction of Tl/I/ with 2-mercaptobenzothiazole into chloroform has been studied. The effect of various parameters on the extraction coefficient value has been evaluated. The stoichiometry of the extracted species obtained from the substoichiometric extraction was found to be 11. This war further supported by the slope ratio method. Decontamination factors of a number of elements in the substoichiometric extraction of Tl/I/ were also obtained.

Abstract  

2-mercaptobenzothiazole has been used for the solvent extraction of Os(IV) in acidic medium. The extraction of Os(IV) was found to be better than 90% over the pH range of 3.0 to 5.0 with an equilibration time of 5.0 minutes. The stoichiometry of metal:reagent determined by substoichiometric extraction and slope ratio method was found to be 1∶4. Decontamination factor for various elements in the substoichiometric extraction of Os(IV) were also evaluated.

Abstract  

The effect of -radiation on waste water solutions containing 2-mercaptobenzothiazole and N-oxydiethylene-2-benzothiazolesulfenamide was studied by UV spectrosocopy, COD, BOD5 and TOC determination and Pitter's kinetic test of biodegradation. No improvement in biodegradability of model solutions was detected and in case of 2-mercaptobenzothiazole colloidal turbidity removable by coagulation appeared.

Abstract  

The reagent 2-mercaptobenzothiazole /2-HMBT/ has been used for the solvent extraction of Ru/III/. The extraction coefficient value of Ru/III/ has been evaluated, based on various parameters such as, effect of molarity of the acid, time of equilibration, time of heating, effect of various solvents and effect of various salts. The stoichiometry of the metal to reagent was determined by the method of substoichiometric extraction of slope-ratio method and was found to be 13. Separation factor and decontamination factor for various elements have also been studied.
