氨基膦酸树脂分离富集贵金属元素性能的研究

The Property of Amiophsphonic Acid Resin for Seperation and Enrichment of Noble Metals

本文简要述叙了氨基膦酸树脂的合成路线,由红外谱图解析及树脂含磷量及金的饱和吸附量的测定,初步判定了络合物的类型和络合比.各元素分配系数的测定表明在 pH2时,可使贵金属元素与贱金属元素分离,且对贵金属 Au,Pt,Pd,Ir 有良好的富集性能.

In this paper,the synthetic method of the aminophosphonic acid resin wassimply described.The complex sorts and ratio were judged by means of analysis of IRspectrum and determination of the contained phosphoric content of the resin as well asadsorption capacity of gold.The distributive coefficient of several kinds of elementswere determined under different pH conditions.The noble metal elements and cheapmetal elements were separated at the definite pH2.The resin has a good performance forthe enrichment of such noble metal as Au,Pt,Pd,Ir.
