DETERMINATION OF SO42- IN WATER BY CONDUCTO-METRIC TITRATION WITH INCREMENT METHOD

摘要: 本文报道直接在水介质中,用电导滴定增量法测定SO42-的含量.可测到5.00×105mol·1-1,相对误差为6.9‰,相对标准偏差为4.6‰.此方法简单、准确、快速.

Abstract: In this paper, a method of conductometric titration with increment for the determination of SO42- in water is reported. The method is applicable to water sample which has a SO42- content as low as 5×10-5mol·l-1,with a relative error of 6.9‰; the relative standard deviation is 4.6‰. This method is simple, accurate and rapid.
