磁性淀粉微球对Ni(Ⅱ)吸附性能的研究
Study on Adsorption of Magnetic Starch Microspheres on Ni(Ⅱ)
摘要
Abstract
The adsorption of magnetic starch microspheres on Ni(Ⅱ) was studied,effect of different reaction time,the initial concentration of Ni (Ⅱ) , the amount of magnetic starch microspheres on adsorption were re-searched, and the adsorption kinetics and thermodynamic behavior was explored. The results showed that the proper conditions of magnetic starch microspheres on Ni(Ⅱ)were as follows:the adsorption time was 80min,the dosage of magnetic starch microsphere was 30mg,the concentration of Ni(Ⅱ) was 80mg/L. The adsorption be-havior of magnetic starch microsphere on Ni(Ⅱ) can be adapted to Freundlich adsorption isotherm equation very well. Study of adsorption kinetics have been shown that adsorption of magnetic starch microspheres on Ni (Ⅱ) can be simulated by pseudo-first order and pseudo-second order kinetic models,but the latter equation being the better.关键词
