新过滤法测定清洁水样中硫酸盐的探讨

Improvement of The Sulfate Determinatiom Method New Filting Method

采用新的过滤法测定清洁水样硫酸盐 ,精密度和准确度较好 ,易于操作 ,空白吸光度既稳定又低 ,其分析指标符合水质分析要求。

The new filting way is introduced to determine and clean sulfate in water samples.The precision degree and accurate degree are good.The blank absorption degree is not only stable but also low.Its analysis index conforms to water quality analysis requirment.
