Sequential micro-scale determination of chlorine (or bromine) and sulphur in organic compounds

Abstract

A comparison is made between the mercurimetric and the potentiometric determination of chlorides. As this comparison indicates the potentiometric titration with silver nitrate has higher accuracy and precision, this procedure has been combined with the bariometric method in order to achieve the sequential determination of halogens and sulphur in the same sample. The results obtained for several samples containing sulphur and chlorine (or bromine) confirm the effectiveness of the proposed method.
