以Cu2+为印迹离子,Cu2+、AM和EGDMA的摩尔比为1∶4∶30,合成了一种具有高选择性和分离富集能力的金属离子印迹聚合物(IIP2)。其在40μg/mL的Cu2+水溶液中对Cu2+的吸附量为12.80 mg/g,印迹因子为1.94。以优化工艺下合成的印迹聚合物(IIP2)制备了印迹固相萃取柱,优化了固相萃取条件,并在此条件下对两个污水样品进行分析,Cu2+的萃取率分别达到93.5%和90.7%。该印迹聚合物有作为Cu(II)分离富集材料的应用前景。
Taking Cu2 + as imprinted ion, the molar ratio of Cu2 +, AM and EGDMA was 1: 4: 30, a metal ion imprinted polymer (IIP2) with high selectivity and separation and enrichment ability was synthesized. The adsorption amount of Cu2 + in the Cu2 + aqueous solution of 40 μg / mL was 12.80 mg / g, and the imprinting factor was 1.94. The imprinted solid phase extraction column was prepared by optimizing the synthesis of imprinted polymer (IIP2), and the conditions of solid phase extraction were optimized. Under these conditions, the two sewage samples were analyzed, the extraction rates of Cu2 + reached to 93.5% and 90.7 %. The imprinted polymer has the potential application as a Cu (II) separation and enrichment material.
