摘要
分别以MCM-41和甲基丙烯酸(MAA)作为基体和功能单体,合成了铑离子表面印迹聚合物Rh-IIP-MAA/MCM-41。选择铂、钯、铁、铜4种金属离子作为干扰离子,对铑离子进行竞争吸附的实验,探究Rh-IIP-MAA/MCM-41对铑离子的选择识别能力,找出了Rh-IIP-MAA/MCM-41吸附铑离子的最佳条件。实验结果表明:最佳条件为Rh-IIP-MAA/MCM-41的用量为40 mg,吸附时间为5 h,吸附温度为25℃,溶液pH值为6。最后进行洗脱和重复使用性能的研究,其性能优良。
Rh-IIP-MAA/MCM-41 was synthesized by using MCM-41 and methacrylic acid(MAA)as matrix and functional monomer respectively.Four metal ions,platinum,palladium,iron and copper,were selected as interference ions for competitive adsorption of rhodium.The selective recognition ability of Rh-IIP-MAA/MCM-41 was explored.The best conditions for Rh-IIP-MAA/MCM-41 to adsorb rhodium were found out:the dosage of Rh-IIP-MAA/MCM-41 was 40 mg,the adsorption time was 5 hours,the adsorption temperature was 25 ℃,and the pH value of solution was 6.Finally,the elution and reusability of the system were studied,and the performance of the system was excellent.
