Adsorption Behavior of Citric Acid on Resin of Chitosan Microspheres
球状壳聚糖树脂对柠檬酸的吸附行为

The resin of chitosan microspheres(RCM) was prepared by using reverse phase suspension cross-linking polymerization.Static adsorption experiments were carried out to study the adsorption kinetics and thermodynamics of citric acid on RCM.The results indicated that the adsorption of citric acid followed the Langmuir isotherm.The Langmuir equilibrium constant(Kb) increased with increasing temperature.The adsorption was a non-spontaneous endothermic process of entropy increasing in thermodynamics of adsorption....
