本工作以聚环硫氯丙烷与(硫代)多甘醇反应合成了五种交联型硫杂冠醚聚合物,并且研究了它们对金属离子的络合性能。结果表明,这些硫杂冠醚聚合物对Ag(Ⅰ)具有较高的络合容量及良好的络合选择性。
In this work, five kinds of cross-linked thia-crown-ether polymers were synthesized by the reaction of poly (cyclic thiochloropropane) with (thio) polyglycol and their complexation with metal ions was studied. The results show that these thio-crown ether polymers have higher complexation capacity and good complex selectivity to Ag (Ⅰ).
