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 (Ni2+, Cr3+, Cu2+) of the surface imprinted adsorbent with Ni2+ as template ion increased considerably. In the presence of the template ion (Ni2+) and other ions in solution, the adsorption capacity and selectivity for the template ion (Ni2+) of the surface imprinted adsorbent were higher than those of another ion (such as Cr3+ or Cu2+). However compared with the surface non-imprinted adsorbent, the adsorption selectivity for the non-template ions (Cr3+ and Cu2+) obviously decreased
