Determination of totaI suIfur in coaI by Eschka-ion chromatography
XUE Cheng
Abstract：In order to simplify the analysis of total sulfur in coal,the total sulfur in coal was converted into sulfate radical which was ana-lyzed by IC(Ion Chromatography)via the reference of GB/ T 214—2007. The proposed method was compared with the national standard method(Eschka method and coulometric titration method)by F test and t test. The experimental results showed that,there was no signifi-cant difference in precision and accuracy between Eschka-ion chromatography method and national standard method.
