摘要
Shredded husks of sunflower, walnut shells and plum stones with particle size less than 0.5 mm were used sep. for the removal Pd2+ and Cd2+ ions from solns. at 25 degrees C. Initial concns. of both ions were changed in the range 0.3-109.4 g/L, resp. Sorbent mass ionic strength, time of adsorption and mixing rate were const. 0.5 g, 0.02 mol/L, 1 h and 120 rpm, resp. Sorption processes were described by Langmuir, Freundlich, Dubinin and Raduszkiewicz models of sorption isotherms. The husk of sunflower showed the best sorption ability.
