锰改性活性炭对Cr(Ⅵ)的吸附研究
Study on Cr(Ⅵ)Adsorption Using Activated Carbon Modified with Mn
摘要
Abstract
Hexavalent chromium is a highly toxic heavy metal. In order to explore the adsorptive behavior of carbonaceous materials for hexavalent chromium in aqueous solution, as the first attempt, activated carbons were modified by Mn2* with different concentrations. Contrast experiments were conducted using original activated carbon and modified activated carbon at different conditions such as pH, temperature, dosages and initial concentrations. The results showed that the activated carbon modified with Mn2+ solution could improve Cr (VI) adsorptive capacity at same conditions, the factors such as pH, temperature, dosage and the initial concentrations affected the Cr ( VI) removal rates. The adsorption isotherms of activated carbon to Cr (VI) had better linear correlation with the Langmuir model.关键词
