- Abstract:
- Surface ion-imprinted poly (allylamine)-silica material (IIP-PAA/SiO2) was synthesized by surface imprinting technique.The effect of sorbent concentration (W0) on Cu(Ⅱ) adsorption was studied using batch experiments.The results showed that the adsorption system exhibited a significant sorbent concentration effect,and adsorption isotherms declined as W0 increased.Results obtained from the tests also indicated that the equilibrium adsorption capacity Qe was not a single function of the equilibrium ion concentration Ce but a function of both Ce and W0.A revised Langmuir model was obtained according to the factor of Ce/W0.Its applicability was examined,and the result showed that the equilibrium capacities under various particle concentrations could be described well by the revised Langmuir model.
