摘要
以酚醛环氧树脂 (F 46)、乙二胺 (EDA)、甘油环氧树脂 (B 62 )为原料合成一种新型树脂 ,研究其对Cu2 +,Ni2 +,Zn2 +和Co2 +的吸附性能 .结果表明 ,该树脂对Cu2 +具有很好的吸附性能 ,吸附量可达 1 2 9mmol·g- 1 ;对Ni2 +有一定的吸附性能 ,吸附量为0 2 3mmol·g- 1 ;而对Zn2 +和Co2 +不吸附 .该树脂可在Cu2 +,Zn2 +和Co2 +等离子共存下选择吸附Cu2 +.液膜扩散是吸附的主控步骤 。
By using novolac epoxy resin,ethylenediamine and glycerol epoxy resin as materials,a kind of new resin was synthesized and its adsorption properties for Cu 2+ ,Ni 2+ ,Zn 2+ and Co 2+ had been studied.The results showed that this resin has good adsorption capacities for Cu 2+ with 1 29 mmol·g -1 and it has some adsorption capacities for Ni 2+ with 0 23mmol·g -1 .But it hardly has adsorption capacities for Ni 2+ and Co 2+ .The resin has good adsorptioin selection for Cu 2+ at the presence of Zn 2+ ,Co 2+ .Liquid film diffusion was major controlling step of adsorption rate which can be described by G.E.Boyd equation.
