Mechanisms of metal adsorption from aqueous solutions by waste tyre rubber

摘要: Abstract The mechanisms of adsorption cadmium(II), mercury(II) and lead(II) on to shredded rubber from old automobile types have been studied it is shown that at least two distinct processes can be involved depending upon the metal being adsorbed. Mercury cadmium uptake are accompanied by displacement zinc therefore probably involve an ion exchange type mechanism. Lead adsorption, in contrast, involves no not competitive with cadium or mercury uptake, suggesting a completely separate mechanism site binding used lead(II).
