污泥基活性炭吸附Cu（2＋）的应用研究
Application of activated carbon made from sewage sludge for adsorbing Cu（2＋）
摘要
Abstract
Using municipal wastewater treatment plant residual activated sludge as raw material,Zncl2 as activator,activated carbon was prepared.Its application as activator for adsorbing Cu2＋ in wastewater was also studied.The effects of the initial pH value of the solution,the initial concentrations of Cu2＋ in the solution on the adsorption capacity were investigated.The absorption isotherm was drawn,and the dynamics equation was also studied.The results indicated that the adsorption performance of activated carbon made from sewage sludge towards Cu2＋ is fine.The optimum pH value is 5.The absorption isotherm well fits the models of both Langmuir and Freundlich equations.The adsorption process is concluded to be a kind of favorable adsorption.The adsorption capacity increases while the solution concentration increases.The adsorption equilibrium time of Cu2＋ is 4 hours.The adsorption process pertains to be second-order kinetics process.关键词
