摘要: 我们曾报导了用D-290阴离子树脂与4-(2-吡啶偶氮)-间苯二酚(PAR)制得PAR螯合形成树脂,简称PAR树脂。其形成不同于一般的螯合形成树脂。从而扩大了获得这类树脂的领域。本文对它的特性进行了研究。

Abstract: The effect of pHon the adsorption behaviour of PARonto D-290 strong basic anion resin was investigated. The rates for the adsorption of Cu(Ⅱ), Gd(Ⅱ) ions on PAR-resin and isotherms for the adsorption of Cu(Ⅱ) on the PAR-resin were measured. The Effect of flow rate on breakthrough volume for the Cu(Ⅱ)-PAR-D-290 system was evaluated. The stability of PAR-resin in different medium was studied.
