油樟叶渣活性炭对磺胺嘧啶的吸附性能
Adsorption Performance of Cinnamomum Longipaniculatum Activated Carbon toward Sulfadiazine
摘要
Abstract
The cinnamomum longipaniculatum activated carbon from leaf residues of cinnamomum longipaniculatum was characterized with fou-rier transform infrared spectroscopy(FTIR)and Brunner-Emmet-Teller(BET)measurements.The effects of the dosage of activated carbon,adsorption time,initial concentration,temperature and pH on the removal of sulfadiazine in water were investigated.The results showed that the removal rate reached 54.4%with the initial concentration of sulfadiazine of 20 mg/L and 700 mg activated carbon.Adsorption performance was improved with adsorption time,and adsorption equilibrium was achieved after 1440 min.Removal rate showed a decreasing trend with increased pH,indicating that acidic environment was conducive to the adsorption toward sulfadiazine.Adsorption capacity rose with elevated temperature and then fell above 35℃.The adsorption fitted well to the quasi-second-order kinetics equation,Weber-Morris intraparticle difussion mod-el,Langmuir and Freundlich adsorption isotherm models,demonstrating that the adsorption was monolayer adsorption,and that the adsorption rate was mainly controlled by both internal particle difussion and surface adsorption.关键词
