摘要
三正辛胺负载泡塑对贵金属有极强的吸附能力。本文通过对三正辛胺负载泡塑对金、铂、钯吸附性能的研究 ,以及 NO-3 和 Fe3 + 离子干扰的消除 ,拟定了金、铂、钯的快速、简便、富集系数高的三正辛胺负载泡塑分离法 ,一次摄谱的测定范围 (10 g样品 )为 :Au0 .1— 5 0 0 0 ng/g;Pt0 .2— 5 0 0 0 ng/g;Pd0 .1— 10 0 0 ng/g。
A high-sensitive and rapid determination of trace Au, Pt and Pd by chemical spectrometry was proposed under the preconcentration with foamed plastics containing trioctylamine. The determination range with 10g sample is 0.1-5000ng/g(Au),0.2-5000ng/g(Pt), 0.1-1000ng/g(Pd)?
