摘要：

The contents of chlorine and sulphur species in commercial portland cement were determined by a two-step sample preparation procedure. The first step was carried out by means of sodium carbonate and peroxide fusion, followed by a second step of electrodialytic neutralisation of the resulting solution. The chloride and sulphate contents were then determined by ion chromatography. The accuracy of the method was checked by analysing a certified standard reference material (SRM). Relative standard deviations were 0.56% and 1.35% for sulphur and chloride determination, respectively. (C) 1999 Elsevier Science Ltd. All rights reserved.
