Abstract
This paper is an effort to seek a cheap and effective sorbent to treat wastewater containing chromium, by investigating the process of chromium ion adsorbed on lignite by the isothermal adsorption equation of Freundlich.The investigation involves using Clapeyron-Clausius equation to give the less adsorption heat with (△H) of only - 5.83 kJ/mol, indicating that the adsorption process is physical one.The paper also introduces the influence of acidity, solution concentration and adsorption time on chromium ion adsorbed on lignite.The results indicate that the equation adsorption capacity of chromium ion on lignite decreases with pH increase.The adsorption of chromium ion on lignite stands at 3.8 mg/g, in the case of pH of 2, the concentration of chromium ion of 50 mg/L and contact time of 100 minutes.The treatment of wastewater containing chromium using lignite is of a certain practical significance.关键词
