摘　　要：研究了一种新的多胺酚醛型铜模板树脂(F44-34-M)对染料酸性橙Ⅱ、活性红Y-3B、直接湖蓝5B的吸附性能以及吸附时间、染料浓度、pH值等因素对吸附性能的影响.结果表明,模板树脂对各种染料的吸附量比非模板树脂均有所增大;模板树脂对染料的吸附符合Boyd液膜扩散控制,其吸附速率较大,表观吸附速率常数在0.012～0.042 min-1之间;树脂对染料的吸附行为可用Langmuir和Freundlich等温式进行描述;树脂对3种染料的吸附均为放热过程.模板树脂对模拟废水的脱色率达92%以上.The Adsorption capability of a novel amino-novolac copper templated resin （F44-34-M ） for watersoluble dyes such as Acid Orange Ⅱ, Reactive Red Y-3B and Directed Sky Blue 5B were studied. The effects of pH value, temperature, time and the concentration of the dyes on the adsorption of the resin for the dyes were also studied. The results show that the adsorption capacities of the templated resin for the dyes are stronger than those of the non-templated resin. The adsorption fits the theory of liquid membrane diffusion by Boyd. The adsorption velocity of the resin for the dyes is fast and the apparent velocity constants should be between 0. 012-0. 042 min^-1. The adsorption can be described by the Langrnuir and Freundlich equations and the adsorption processes for the dyes are exothermic. Decolorization rate of the resin for simulated wastewater dyes exceeds 92%.
