摘　　要：本文以与过量形成ＢａＳＯ＿４沉淀反应为基础，较详细地讨论了反应条件、从而拟定了用ＡＡＳ和ＩＣＰ－ＡＥＳ间接测定天然水中的方法、确定了方法的精密度，ＡＡＳ法的ＲＳＤ％为１．５，ＩＣＰ－ＡＥＳ法为３．２．两种方法对比分析的结果接近，误差为１．０％（相对）。用于天然水中的测定，获得满意的结果。This paper discusses the reaction conditions which are required for precipitating BaSO_4 from wich excess Two methods of AAs and ICP- AES are proposed for indirect determination of sulfate in natural water.The procedural precisions are 1. 2% RSD (for AAS)and 3.2% (for ICP- AES).A comparative analysis of the two methods shows that the results are alike, except for relative error of 1.0%,The proposed methods have been used to determine in natural water with satisfactory re-
