摘要
以甘油和乙醇为主的混合液作为稳定剂,用硫酸钡光度法测定水中硫酸盐含量,所得标准曲线线性系数为0.9965,线性范围10mg/L～200mg/L,加标回收率为97.85%～101.02%,变异系数CV%≤5。
This paper analyzes how to mensurate sulfate content in water by means of pgotometry of vitriolic barium using flycerion and ethanol as tranquilization. The results of the research are as follows:linear quotiety:0.9965;linear range:10mg/L～200mg/L;ration of retrieve:97.85～101.02%;variance quotiety;CV%≤5.
