通过制备的方法获得菌丝体表面分子印迹吸附剂,本文系统的分析和探讨了针对模板金属离子菌丝体表面分子印迹吸附剂的吸附选择性。通过实验研究证明,菌丝体表面分子印迹吸附剂如果是以Ni2+为模板制备的,相对于非印迹吸附剂来讲,其对Cr3+、Cu2+、Ni2+的吸附容量以及吸附速率的提高幅度都是非常大的。而菌丝体表面分子印迹吸附剂相对于具有Ni2+金属离子混合溶液来讲,其对Ni2+的选择性以及吸附容量要比含有诸如Cu2+以及Cr3+的金属离子提高的都要明显很多;印迹吸附剂相对于非印迹吸附剂来讲,其在吸附非模板金属离子Cu2+以及Cr3+时具有明显降低的选择性。
The mycelial surface molecularly imprinted adsorbent was obtained by the method of preparation. The adsorption selectivity of molecularly imprinted adsorbent on the surface of mycelium of template metal ion was analyzed and discussed in this paper. Experimental studies have shown that, if the molecular imprinting adsorbent on the surface of mycelium is prepared using Ni2 + as a template, its adsorption capacities for Cr3 +, Cu2 + and Ni2 + and the rate of increase of the adsorption rate are all very high compared to non-imprinted adsorbents big. The mycelial surface molecularly imprinted adsorbent has significantly more selectivity for Ni2 + and higher adsorption capacity than metal ions such as Cu2 + and Cr3 +, compared with Ni2 + mixed solution. In the case of non-imprinted adsorbents, it has significantly reduced selectivity for the adsorption of non-template metal ions Cu2 + and Cr3 +.
