摘　　要：合成了三乙烯四胺交联的甘油双缩水甘油醚树脂 ,并研究了该树脂对 Cu2 +、Ni2 +、Zn2 +、Co2 +的静态吸附性能和吸附机理。结果表明 ,该树脂对 Zn2 +、Co2 +的吸附是单一吸附机理 ,而对 Cu2 +、Ni2 +的吸附则为多重吸附机理 ,对4种离子的等温吸附过程均符合 Freundlich方程。对 Cu2 +、Ni2 +、Zn2 +、Co2 +的吸附容量可分别达 0 .61、0 .3 2、0 .0 6和 0 .2 3 mmol g。A new kind of resin, glycerol epoxy resins crosslinked by tri ethylenetetramine, was synthesized, and its adsorption properties and adsorption mechanism for Cu 2+ , Ni 2+ , Zn 2+ , Co 2+ were investigated. The experimental results show that the adsorption for Co 2+ and Zn 2+ , is mono mechanism, and for Cu 2+ and Ni 2+ is multi mechanism. All adsorption isotherms can be described by Freundlich equations. The adsorption capacities for above mentioned metal ions are 0.61, 0.32, 0.23 and 0.06 mmol/g respectively. This resin will have wide use in separating or treating metal ions which are contained in industry waste water.
