Adsorption and desorption of cd
... 23% of Cd was adsorbed at 15 min, while 32%, 37%, and 55% of Cd was adsorbed at reaction times of 24 h, 7 days, and 4Fig. 1. Percent Cd adsorption by the phosphate-treated goethite () and untreated ... accelerated the adsorption kinetics. The adsorption edges shifted to lower pH substantially in the presence of phosphate, indicative of enhanced Cd adsorption. The adsorption of Cd did not reach ... absence of phosphate. The en-hanced Cd adsorption could be attributed to the re-duction of the pHzpc(zero point of charge) of goethite and surface potential after the phosphate treatment(Kuo and...
