摘    要:采用制备得到的菌丝体表面分子印迹吸附剂;系统研究了菌丝体表面分子印迹吸附剂对模板金属离子的吸附选择性。结果表明:与非印迹吸附剂相比;以Ni+为模板制备的菌丝体表面分子印迹吸附剂;对Ni+、Cu+与Cr3+的吸附速率和吸附容量都有较大幅度的提高。对于含有Ni+的金属离子混合溶液;菌丝体表面分子印迹吸附剂对Ni+的吸附容量和选择性都比另一种金属离子(如Cr3+和Cu+)明显提高;与非印迹吸附剂相比;印迹吸附剂对非模板金属离子Cr3+和Cu+的选择性明显降低。

关 键 词:菌丝体表面分子印迹吸附剂  选择性吸附  金属离子  分子印迹  生物吸附

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.
Keywords:surface imprinted adsorbent   selective adsorption   metal ion   molecular imprinting   biosorption
