研究了酰胺/膦酸酯型树脂483C1[CONHCH2CH2P(O)(OR)2]从盐酸中吸金的化学问题,结果表明平衡服从Freundlich吸附等温式, AuCl4^-以缔合机制吸着; 测得了AuCl4^-的内扩散系数以及HCl-硫脲为解吸剂时的有关动力学参数; 还研究了AuCl4^-的柱穿透曲线.

The adsorption of Au3+ (as AuCl4-) by the title resin from HCl solution involved an association mechanism and was described by the Freundlich equation. The desorption and breakthrough of AuCl4- upon elution by HCl-thiourea solution were studied.
