摘要
采用化学键合的方式合成了含氨基硫脲的螯合泡沫塑料,研究了CPF—Ⅲ型螯合泡沫塑料分离富集贵金属金、银、钯的各种条件,试验了30多种离子对分离富集金、银、钯的影响,成功地应用于复杂试样中金、银、钯的分析。
The synthesis of a chelate foaming plastics containing amino-thiourea as functional chelating group is reported in this paper. Various optimum conditions for the separation and concentration of Au, Ag, Pd were studied. The interferences of more than 30 coexisting ions were also tested. The proposed method has been applied to the analysis of some complex samples containing gold silver and palladium.
