Abstract
Alkali metal (potassium and lithium) titanates were synthesized and em ployed for the efficient removal of Cd(II) ions from aqueous solutions using the radiotracer technique. The possible mechanism involved at t he solid/solution interface was deduced with the help of various physi co-chemical data, i.e. effect of adsorptive concentration temperature and pH. The effect of added cations and H+ (HCl/H2SO4) in the uptake p rocess was also seen. The radiation stability of these materials in th e adsorption process was assessed by employing a 11.1 GBq (Ra-Be) neut ron source having an integral neutron flux of 3.85 x 10(6) n.cm(-2) s( -1) and associated with a nominal gamma-dose of ca. 1.72 Gy/h.
