| Abstract: | The method for detrmination of trace selenium in natural water and waster water by GFAAS is studied in this paper.Natural water or waste water was digested by HNO_3—HCLO_4 then extracted and enriched with APDC and MIBK.determined by GFAAS.The detection limit was 0.7μg·L~(-1).Result is very satisfactory. |
