【摘要】 对微孔木薯淀粉吸附次甲基兰的特性进行了研究,发现微孔淀粉对次甲基兰的吸附遵循Langmuir吸附等温方程式,其吸附速率方程为:A=0.4228t0.243。淀粉颗粒表面ζ电位决定其对次甲基兰的饱和吸附量,ζ负电位增大,吸附量增加;当ζ正电位增大,则吸附量下降。更多还原

【Abstract】 The property of microporous tapioca on the adsorption of methylene blue was studied in this paper.It was observed that the adsorption of methylene blue obey The Langmuir adsorption isotherm equation ,the adsorptive speed equation of microporous tapioca were deduced as A=0.4228t^0.243 .It had been found that the zeta potential of the microporous tapioca had a great effect on adsorption capacity of methylene blue,the adsorption increased with negative zeta potential increasing,while the adsorption decreased with positive zeta potential increasing.更多还原
