磷酸改性和普通核桃壳对水中Cr（VI）的吸附
Adsorption of Cr(VI) in Water with Phosphoric Acid Modified and Ordinary Walnut Shell
摘要
Abstract
A comparison between the effects of ordinary walnut shell and phosphoric acid modified walnut shell on adsorption of Cr(VI) was carried out.The experimental results show that owing to larger surface void of modified walnut shell its adsorption of Cr(VI) was better.when the temperature was 35℃,adsorbent parti⁃cle size was 1.0-1.6 mm,shaker shock rate was 200 r/min,dosage of walnut shell was 0.80 g,the Cr( VI) re⁃moval rate reached 99. 4%. The fitting of adsorption isotherm and kinetics model showed that, Langmuir iso⁃therm model could reflect the adsoption process of modified walnut shell;and both the adsoption processes of ordinary and modified walnut shell accorded with the pseudo two order kinetic equations.关键词
