摘　　要：将TRPO(三烷基氧化瞵)负载在泡沫塑料上制得了新型TRPO负载泡塑。采用负载泡塑分离富集,石墨炉原子吸收法测定痕量金。实验结果表明,本法对标准物质的测定值与标准值基本吻合,相对误差(RE)为-5.33%~2.35%,方法精密度(RSD,n=8)为0.98%~3.54%。TRPO loaded on foam was prepared with TRPO loading on the foam plastic. Trace gold was detected by Graphite Furnace Atomic Absorption Spectrometry after adsorption With TRPO loaded on Foam. The method was applied to the determination for standard reference samples and the results were basically in agreement with certified values with relative error of-5.33 %~2.35 %(RE) and precision of 0.98 %~3.54 %(RSD, n=8).
