| Abstract: | 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- |
