本文研究了Ｄ_００１大孔阳离子强酸树脂从Ｈ_２ＳＯ_４－ＣＳ（ＮＨ_２）_２溶液中，富集及分离Ａｕ（Ｉ）、Ａｇ（Ｉ）的性能。表明在ｐＨ＝２．０左右，树脂对Ａｕ（Ｔｕ）￣＋_２、Ａｇ（Ｔｕ）￣＋_２（Ｔｕ＝硫脲）有良好的吸附性能，Ａｕ和Ａｇ的吸附容量分别为６１．１８ｍｇ／ｇ－Ｒｅｓｉｎ和９９．１１ｍｇ／ｇ—Ｒｅｓｉｎ。负载柱上的Ａｕ、Ａｇ可分别用ＮａＣＮ—ＮａＯＨ和Ｈ_３ＢＯ_３－ＮａＯＨ－Ｎａ_２Ｓ_２Ｏ_３定量洗脱。可进行一定程度的Ａｕ、Ａｇ分离。
In this paper, D_001 macroporous cationic strong acid resin was used to enrich and separate Au (I) and Ag (I) from H_2SO_4-CS (NH_2) _2 solution. The results showed that the adsorption capacity of Au (Tu) ~ + _2 and Ag (Tu) ~ + _2 (Tu = thiourea) was good at pH = 2.0. The adsorption capacities of Au and Ag were 61.18mg / Resin and 99.11 mg / g-Resin. The column of Au and Ag can be quantitatively eluted with NaCN-NaOH and H_3BO_3-NaOH-Na_2S_2O_3 respectively. Can be a certain degree of Au, Ag separation.
