Abstract:

Using a new chitosan molecular imprinted adsorbent based on the mycelium of waste biomass（surface imprinted adsorbent）;the adsorption selectivity of the surface imprinted adsorbent for the template ion was studied.The results showed that;compared with the surface non-imprinted adsorbent;the adsorption capacity and rate for three ions（Ni+;Cr3+;Cu+）of the surface imprinted adsorbent with Ni+ as template ion increased considerably.In the presence of the template ion（Ni+）and other ions in solution;the adsorption capacity and selectivity for the template ion（Ni+）of the surface imprinted adsorbent were higher than those of another ion（such as Cr3+ or Cu+）.However compared with the surface non-imprinted adsorbent;the adsorption selectivity for the non-template ions（Cr3+ and Cu+）obviously decreased.
