| 摘 要： | 将样品用王水分解定容静置后,采用阴离子树脂—活性炭混合吸附体系进行静态吸附,将吸附体高温灰化后再以王水分解定容,用石墨炉原子吸收光谱仪测定溶液中的铂、钯.该方法检出限为铂0.084ng/g,钯0.025 ng/g,回收率铂为95％～ 103％,钯为95％～ 98％.

| Abstract: | The sample is decomposed with aqua regia, volume settled, still placement, then still absorption with anion gum-active carbon mixed absorption system. After high T ashing of the absorption matter, it is decom- posed with aqua regia, volume settled. The Pt, Pd in solution are examined with graphite atomic absorption spec- trometer. The detection limit Pt 0. 084ng/g; Pd 0. 025ng/g; the recovery Pt 95 ~ 103% ; Pd 95 ~98%. |
