摘要:Removal of rhodamine 6 G 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 6 G, contact time and pH values were discussed. Adsorption thermodynamics and kinetics were also investigated. Maximal adsorption capacity was 710 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.
