摘要: A batch adsorption system was applied to study the of Cd 2+ ions from aqueous solution by Hevea Brasiliensis, HB leaf powder. The capacities and rates onto powder were evaluated. Langmuir Freundlich models describe isotherms constants. Equilibrium data agreed well with model. kinetic experimental correlated pseudo-second-order model, indicating that chemical sorption rate-limiting step.
