摘要: 以大孔交联聚丙烯酸甲酯为原料,通过二乙烯三胺胺化和铜络合反应,合成了以交联聚丙烯酸甲酯为载体的二乙烯三胺/铜(Ⅱ)络合物,研究了这类高分子铜络合物在不同条件下对尿素的吸附性能.结果表明,高分子铜络合物对尿素的吸附主要是通过铜(Ⅱ)与尿素之间的配位作用进行的.在尿素浓度为130mg/dL,于pH为7的NaH2PO4-Na2HPO4缓冲溶液中,28℃时吸附4h,以交联聚丙烯酸甲酯为载体的二乙烯三胺/铜(Ⅱ)络合物对尿素的最大吸附量可达71.5mg/g.

Abstract: Some polymeric diethylenetriamine/Cu(Ⅱ) complexes supported by porous crosslinked poly (methyl acrylate) were synthesized as the adsorbents for urea and their properties in adsorbing urea were studied.The results showed that the polymeric complexes adsorbed urea through coordinate bond of urea to the centric ion.The largest capacity of the complexes was determined as 71.5 mg/g when the adsorption was performed at 28℃ in the urea solution with concentration of 130 mg/dLin a buffer of NaH2PO4-Na2HPO4(pH=7.0).
