PAR螯合形成树脂特性的研究

The Characteristic of PAR Chelate Forming Resin

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^([1]),简称PAR树脂。其形成不同于一般的螯合形成树脂^([2-6])。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。(一)实验1.试剂D-290大孔强碱性阴离子树脂(氯型)40-500,南开大学化工厂产品。

The effect of pH on the adsorption behaviour of PAR onto 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.
