Determination of Sulfur in Solids by Constant Current Coulometric Titration Following Combustion.

摘要

A method for determination of sulfur in solid materials by combustion in induction furnace, followed by constant current coulometric titration of the sulfur dioxide produced, is described. The method is applicable to samples with sulfur contents of 80 ppm to 20,000 ppm. Its feasibility was checked on the NBS and Leco steel samples. The results are in good agreement with the specified values. (Atomindex citation 19:066334)
