| Abstract: | A method for direct determination of sulfate in natural mineral water by ICP-AES was established. The samples were treated by hydrochloric acid.The results showed that the detection limit was 0.01mg/L, with 95%~103% recovery,RSD was below 1.0%, and the standard deviation (RD) was less than 5%. |
