Biosorption and desorption of Cd2+ from wastewater by dehydrated shreds of Cladophora fascicularis
摘要
Abstract
The adsorption and desorption of algae Cladophora fascicularis and their relation with initial Cd2+ concentration,initial pH,and co-existing ions were studied.Adsorption equilibrium and biosorption kinetics were established from batch experiments.The adsorption equilibrium was adequately described by the Langmuir isotherm,and biosorption kinetics was in pseudo-second order model.The experiment on co-existing ions showed that the biosorption capacity of biomass decreased with an increasing concentration of competing ions.Desorption experiments indicated that EDTA was efficient desorbent for recovery from Cd2+.With high capacities of metal biosorption and desorption,the biomass of Cladophora fascicularis is promising as a cost-effective biosorbent for the removal of Cd2+ from wastewater.关键词
