中文摘要：

研究白腐真菌粉末对Zn2＋的吸附效果、影响因素及其吸附机理。结果表明，35min后吸附过程基本完成，pH适宜范围为5-6，Zn2＋吸附率随着Zn2＋初始浓度增大而提高，且在Zn2＋初始浓度为25mg／L，吸附剂用量为2．5g／L，pH为5．5的最佳条件下，Zn2＋吸附率达到98．01％。与原白腐真菌相比，用0．8mol／LNaOH对菌样进行预处理，Zn2＋的吸附率可提高10％左右。运用扫描电镜（SEM）、X射线衍射仪（XRD）和红外光谱仪（FTIR）对Zn2＋吸附前后的白腐真菌粉末进行表征。结果表明，白腐真菌表面粗糙，孔隙多。吸附Zn2＋的过程中，白腐真菌表面的-OH和-PO4与Zn2＋发生络合反应，生成的产物主要为磷酸锌和氢氧化锌。

英文摘要：

Efficiencies, influence factors and absorption mechanism of Zn2＋ adsorption by white rot fungi powder were investigated. Results showed that the process for adsorption of Zn2＋ can be basically finished in 35 min, with suitable pH in range of 5-6, and adsorption rate of Zn2＋ increased with increase of initial concentration of Zn2＋. Under the optimal reaction conditions as initial concentration of Zn2＋ 25 mg/L, adsorption dosage 2.5 g/L and pH value 5.5, the adsorption rate of Zn2~ was 98.01%. In comparison with the untreated fungus, the fungus treated with 0.8 mol/L NaOH solution, the adsorption rate of Zn2＋can increase about 10%. The fungus surface was characterized by scanning electron microscopy, X- ray diffraction and infrared spectroscopy, results indicated that the fungus surface was rough and porous.-OH,-PO4 and Zn2＋ involved in complexation reactions in the processof Zn2＋ adsorption by the fungus, with main products as Zn3（PO,）2 and Zn（OH）2.
