研究了海藻酸钠接枝聚丙烯酸2-丙烯酰胺-2-甲基丙磺酸/高岭土(SA-g-P (AA-co-AMPS)/KL)复合树脂对罗丹明6G 染液的吸附性能。探讨了染料初始浓度、吸附时间、pH 值对吸附性能的影响,并对吸附结果进行热力学和动力学拟合。结果表明,复合树脂对罗丹明6G 在实验条件下的最大吸附量为710 mg/g,吸附过程是自发的,且同时符合 Freudlich方程和 Redlich-Peterson 方程,动力学符合拟二级动力学方程。

Removal of rhodamine 6G from aqueous solutions using sodium alginate graft poly (acrylic acid-co-2-acrylamido-2-methyl-1-propane sulfonic acid )/kaolin composite hydrogel was sudied.The factors influencing the adsorption capacity such as initial concentrations of rhodamine 6G,contact time and pH values were discussed. Adsorption thermodynamics and kinetics were also investigated.Maximal adsorption capacity was 7 1 0 mg/g.It showed that the adsorption process was spontaneous and the adsorption isotherms were in good agreement with both Freudlich and Redlich-Peterson equations,the kinetics fit pseudo-second-order equation.
