摘　　要：以三聚硫氰酸为原料,邻苯二甲酸二辛酯(DOP)为增塑剂,聚氯乙烯为大分子骨架,在MgO的存在下,合成得到了三聚硫氰酸交联聚氯乙烯树脂.对交联树脂吸附重金属离子的性能研究表明,合成树脂对Cu2+的吸附容量及选择性最大,在实验条件下吸附量达到1.056mmol/g;对其他金属离子吸附量很小,甚至不吸附.Polyvinyl chloride resin crosslinked with trimerization thiocyanic acid was synthesized by using trimerization thiocyanic acid and polyvinyl chloride as the starting materials and dioctyl phthalate as the plasticizer in the presence of MgO.The adsorption capacities of the crosslinked resin for Cu^2＋,Zn2＋,Mn2＋,Ag＋ and Pb2＋ were evaluated.It was found that the crosslinked resin had the maximum adsorption capacity and highest selectivity for Cu^2＋,exhibiting maximum adsorption capacity of 1.056 mmol/g for Cu^2＋.However,it possessed lower or even zero adsorption capacity for other heavy metal ions.
