| Abstract: | Comparison of two determination methods for the chlorine in coal between high performance liquid chromatography(HPLC) and potassium sulfocyanate titration was studied.A weighed specimen was burned in a combustion bomb or mixed with eschka mixture and heated at a specified temperature in an oxidizing atmosphere,and analyzed by the two methods.Based on the analysis of the standard reference material GBW 11118,GBW 11119,GBW 11120 and comparing standard deviation and relative errors of the results with the t-test,there was no conspicuous difference between the two methods. |
