Kinetic research on adsorption of chromium ion with Huolinhe lignite
摘要
Abstract
This paper is devoted to an insight into the process of chromium ion (Ⅵ) adsorbed with Huolinhe lignite, depending on the dynamic adsorption experiment and using the Lagergren pseudo first order, Lagergren pseudo second order and Elovich equations to investigate the kinetic process of chromium ion (Ⅵ) adsorbed with Huolinhe lignite. Results show a closer match between experimental data and Lagergren pseudo first model during the concentration ranging from 10 mg/L to 90 mg/L in the case of room temperature 25 ℃, pH of 2, and all the correlation coefficients are found to be above 99%. And within this concentration range, the Lagergren pseudo first model gives a more accurate description of all the adsorption process of chromium ion (Ⅵ) with Huolinhe lignite than Lagergren pseudo second order and Elovich model.关键词
