Determination of total sulfur content of sedimentary rocks by a iodometric titration method

Abstract

Total sulfur content has been determined in sedimentary rocks by a iodometric titration method. The sulfur content in GSJ and USGS standard samples could be analyzed with good precision. A high halogen content in the samples, however, seriously affects the analysis: e. g., values of the sulfur content decrease significantly, when NaCl is more than 5 mg.
