造纸污泥基生物炭的制备及对甲基橙的去除
Preparation of Biochar-based Paper Sludge and Its Application in Absorption on Methyl Orange
摘要
Abstract
In this study,iron-doped biochar(PBC)was prepared by one-step pyrolysis with paper mill sludge(PMS)containing iron salt,and the adsorption properties for methyl orange were studied.The results showed that the biochar material obtained at 800℃ had the best methyl orange removal performance at pH value of 3 and adsorption time of 24 h.The adsorption of methyl orange by PBC-800 conformed to the quasi-second-order kinetic model and Langmuir adsorption model.The adsorption process of PBC-800 on methyl orange was chemical ad-sorption,and the maximum adsorption capacity was 352.05 mg/g.关键词
