Adsorption Mechanism of Toxic Metal Ions by Clay (attapulgite)


A series of adsorption tests were conducted to analyze the sorption capacity of attapulgite. Ions such as cobalt, nickel, lead and cadmium were adsorbed from waste solutions onto attapulgite surface. Adsorption depletion tests were performed as a function of solid to liquid ratio, conditioning time, heavy metal ion concentration, and pH to identify the mode… (More)
