高分子多孔微球富集-HPLC法测定水体中的有机磷
Macroporous Polymer Enrichment and HPLC Determination of Organic Phosphorus in Waste Water
【摘要】 本文提出应用国产高分子多孔微球-GDX系列富集-反相高效液相色谱法测定废水中久效磷、乐果、甲基对硫磷三种有机磷农药分析方法。三种不同型号色谱固定相(GDX-102,GDX-301和GDX-501)对水体中ng/mL级久效磷、乐果和甲基对硫磷的富集效率分别达到85%、82%和93%以上。采用μ-BondapakC18作固定相,以60%甲醇水溶液作流动相,对三种有机磷农药的分离度可达到1.2以上。本法用于分析水体中有机磷农药,结果令人满意。
【Abstract】 Monocrotophos,dimethoate and methyl parathion of 10-6 level in waste water were enriched by GDX-102,GDX-301 and GDX-501 with an enrichment rate of 85%, 82% and 93% respectively,then they are determined by HPLC on a μ-Bondapak C18 column using 60% solution of methanol as eluent.
