廉价生物吸附剂的制备及其对刚果红吸附研究OA北大核心CSTPCD
Preparation of Low Cost Biosorbent and Its Biosorption Properties for Congo Red from Aqueous Solution
利用烟草废水(tobacco wastewater,TWW)培养青霉菌LY7获取菌丝体,以灭活茵丝体为材料制备廉价真菌吸附剂PLYB.研究了PLYB的表面特征及其对水溶液中刚果红(Congo Red,CR)的吸附行为,考察了PLYB加入量、温度、pH、吸附时间、染料初始浓度等因素对CR吸附效果的影响,结果表明,PLYB对CR的吸附过程符合Langmuir吸附等温式,吸附过程可用准二级动力学模型较好的描述.根据Langmuir吸附等温线,30℃和p…查看全部>>
A low cost biosorbent PLYB was prepared from the inactive biomass of fungus Penicillium LY7, which was capable of utilizing tobacco wastewater as a substrate without any addition of nutrients. The characterization of the biosorbent surfaces, biosorption kinetics, isotherm models and the effects of various experimental factors were investigated. The kinetics and equilibrium biosorption were well described by pseudo-second-order kinetic and Langmuir isotherm…查看全部>>
