研究了强酸性苯乙烯系阳离子交换树脂００１－Ａ在ｐＨ＝ ２．０的Ｈ２ＳＯ４－ ＣＳ（ＮＨ２）２－ Ｈ２Ｏ２ 体系中，吸附、富集硫脲金的性能。结果表明，该树脂对硫脲金离子Ａｕ（Ｔｕ）＋２ （Ｔｕ＝ 硫脲）具有吸附率高，吸附容量大等优异性能。Ａｕ 负载柱可用Ｎａ２Ｓ２Ｏ３ 溶液定量洗脱，用过的树脂可再生。
The performance of strong acid styrene cation exchange resin 001-A adsorbing and enriching thiourea gold in H2SO4-CS (NH2) 2-H2O2 system with pH = 2.0 was studied. The results show that the resin has the excellent performance of high adsorption rate and large adsorption capacity for thiourea gold ion Au (Tu) +2 (Tu = thiourea). The Au loading column can be quantitatively eluted with Na2S2O3 solution, and the used resin can be regenerated.
