以自制海藻酸纤维为吸附剂,研究它对臧红T的吸附性能。用准一级动力学方程、指数函数方程、准二级动力学方程、粒子扩散方程、Elovich方程和双常数方程对不同染料浓度、吸附时间的曲线进行拟合。结果表明,后四种方程的拟合度较好,这说明此吸附是复杂的非均相扩散吸附过程,存在化学吸附,且膜扩散和颗粒内扩散共同控制吸附速率。

The removal of Safranine T from aqueous effluents by alginic acid fibre was studied.The kinetics of sorption were analyzed by six kinetic models of the Pseudo-first-order model,the exponential function model,the pseudo-second-order model,the intra-particle diffusion model,the Elovich kinetic equation,and the double-constant equation.The results showed that the last four models were applied to fit the experimental kinetic data.The adsorption was a complex heterogeneous diffusion process,with chemical adsorption.Intra-particle diffusion and extra-particle diffusion both controlled the adsorption rate.
