【Abstract】 The continuous adsorption of Cd 2+ on vermiculite was studied,in addition the modification and regeneration of the adsorbent were inspected.The results showed that vermiculite had a strong adsorption effect and the successive operation of adsorption to Cd 2+ was practical;The adsorption capacity of vermiculite can be remarkably increased when modified with 1mol/L HCl or 1mol/L NaCl.Moreover the adsorbent can be readily regenerated with 1mol/L NaCl and used repeatly.更多还原
