| Abstract: | 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. |
