摘　　要：将三烷基氧化膦(TRPO)负载在泡沫塑料上制得了TRPO负载泡塑。以火焰原子吸收光谱法(FAAS)为检测手段,研究了负载泡塑对微量金的静态吸附性能。建立了负载TRPO泡塑分离富集-FAAS测定微量金的方法。方法精密度(RSD,n=10)在1.23%—8.22%之间,通过对标准物质的分析,测量值与标准值基本一致。TRPO loaded on foam was prepared with TRPO loading on the foam plastic.The static absorbability of loaded foam plastic to trace Au3＋ was detected by flame atomic absorption spectroscope（FAAS）.A method for determination of trace gold by flame atomic absorption spectroscope（FAAS） after separation and pre-concentration by TRPO loaded on foam plastic was developed.The method was applied to determination for standard reference samples,and the results were basically in agreement with certified values with precision of 1.23%-8.22%（RSD,n=10）
