一次盐水Ca^(2+)含量对SO_4^(2-)测定结果的影响

Influence on determination result of SO_4^(2-) by Ca^(2+) content in primary brine

通过对盐水中SO_4^(2-)含量测定结果异常原因的分析,提出Ca2+含量会对SO_4^(2-)分析结果产生影响,指出了分析SO_4^(2-)含量时应注意的问题。

Through the analysis of reasons of abnormal determination results of SO4^2- content in brine, the infulence on anlysis results of SO4^2- from contents of Ca^2＋ were put forward. And the attention problem of SO4^2- contents analysis were point out.
