| Abstract: | A method for indirect determination of sulphate in water by using ICP-AES has been proposed. the method is based on determination of excess of barium ion in filtrate after the sulphate in the sample is completely precipitated by using a known amount of barium ion. The relative standard deviation(RSD) of this method is 2%,and the recovery is in the range of 99 -101.5%. |
