摘要
本文报导了大孔自偶合树脂的合成方法.该树脂在稀HCl介质中,对常见元素的离子,如Fe^(3+),Mn^(2+),Co^(2+),Ni^(2+),Cu^(2+)等吸附极少,而对Au^(3+)的吸附很高,其静态吸附容量可达0.81mmol/g;在0.3mol/L HCl介质中其分配系数为5995.吸附动力学特性好.树脂吸附500μg Au^(3+)后用50m15%硫脲—0.1mol/L HCl洗脱液可以定量洗脱.本树脂可用于共生矿石中金的分离和富集,也可用于废电镀液中金的回收.
In this papen the synthesis and chelating properties of self-coupling chelating resin with macro-pores were studied. It has heen shown that the adsorption selectivity and chelating capacity of self-coupling resin with Au3+ are good. Using self-coupling chelating resin Au3+ can be concentrated and separated from the solutious containing Co, Ni, Cu, Mu, Cr, Fe ions. Using the resin race Au8+ from the wasted plating bath can be recovered satisfactorily.
