【Abstract】 The feasibity of gas chromatographic determination of dieldrin in sea water was examined by the following processes: dieldrin in sea water was accumulated onto a domestic 1300 （1） resin and the extract was purified and separated in a combined SiO₂-Al₂O₃-Na₂SO₄ column, and then concentrated with nitrogen gas and determined by gas chromatography.Good recoveries were reached by this method with a mean recovery of 86%, and a standard deviation of 5%. The results show that this method is acceptable to determining dieldrin of ng/L level in sea water.更多还原
