含膦树脂的制备及其在模拟废水中回收功夫酸的应用

Preparation of Phosphine-containing Resins and Their Application in the Recovery of Lambda Cyhalotric Acid in Simulated Wastewater

研究了4种不同含膦树脂在酸性介质中对功夫酸的吸附行为。结果表明,含膦单体20%的聚苯乙烯树脂对功夫酸具有较好的吸附性。其中溶液最佳吸附pH在2.0~3.0之间,吸附50min达到平衡,温度升高有利于吸附。研究表明4种含膦单体树脂对功夫酸的饱和吸附容量分别11.42μg/g、11.3μg/g、8.96μg/g、4.42μg/g。

The static adsorption behavior of four different phosphine-containing resins on Lambda Cyhalotric Acid in acidic media was studied.The results showed that the 20%phosphine monomer polystyrene resin had good adsorption to kung fu acid.Among them,the optimal adsorption pH of the solution is between 2.0~3.0,and the adsorption reaches equilibrium for 50 min,and the temperature increase is conducive to adsorption.Studies have shown that the saturated adsorption capacity of four phosphine-containing monomer resins on Lambda Cyhalotric Acid were 11.42μg/g,11.3μg/g,8.96μg/g and 4.42μg/g,respectively.
