摘要:
常规无机化学水分析认为Sr2+、Ba2+与SO42-不能共存,但在高矿化度地层水中既检出Sr2+也检出SO42-的现象屡见不鲜,究其原因是高矿化度地层水中的盐效应所造成的影响。对高矿化度地层水分析既要检测Sr2+、Ba2+含量也要检测SO42-含量。

Abstract:
It is thought impossible that Sr2+, Ba2+ and SO42- can coexist in inorganic chemical analysis on water. However, it is of common occurrence that Sr2+ and SO42--can be detected simultaneously in highly saliniferous formation water, which is caused by the salt effect in it. Therefore, the analysis of highly saliniferous formation wa- ter should be done including the detection of the content of Sr2+, Ba2+ and SO42- simultaneously.
Key words:  salt effect  formation water  salinity  solubility  SrSO4  BaSO4
