| 摘 要： | 以丙烯酰胺(AAm)、丙烯酸(AAc)合成了单体配比分别为1，2、1／1、2，1的AAm/AAcc水凝胶，采用分光光度计法研究了此水凝胶对水溶性单价阳离子染料碱性藏花红的吸附特性，测定了它们的吸附动力学曲线和吸附等温线：探讨了水凝胶单体组成对该染料吸附性能的影响：并且用静电场理论解释了解吸后水凝胶更优的再吸附特性，研究表明，AAm，AAc水凝胶可作为染料污水处理中一种良好的吸附剂。

| Abstract: | In this study, Acrylamide (AAm)/Acrylic Acid (AAc) hydrogels have been synthesized from AAm and AAc monomers in three different composition (AAm/AAc mole ratios: 1/2,1/1,2/1). Poly(AAm/AAc) hydrogels were used to adsorb a water-soluble monovalent cationic dye such as Safranine T (ST) and the adsorption behavior was studied by spectrophotometer. The adsorption kinetics curves and adsorption isotherms were established for the ST and hydrogel systems. The influence of the monomer composition on the adsorption of the systems was investigated as well. The better readsorption ability of desorption hydrogels can be explained by the static electric field theory. It is concluded that poly(AAm/AAc) hydrogels may be used as an adsorbent for decolorization of textile wastewaters. |
