摘要:

为探究重金属镍的处理及菌糠资源过度浪费的问题,利用杏鲍菇菌糠、姬平菇菌糠、香菇菌糠为原料制备生物炭(PEBC、PGBC和LEBC),通过扫描电镜(SEM)、X-射线粉末衍射(XRD)和比表面积分析(BET)对其结构进行表征,并采用Zeta电位测定探究其吸附机理,同时通过吸附实验对比3种菌糠生物炭对镍离子的吸附影响。结果表明:3种菌糠生物炭均具有不规则孔隙,且表面附着较多的矿物质晶体。综合而言,PEBC的吸附效果最好,去除率超99%且最大平衡吸附量可达122.89 mg/g。采用废弃菌糠探究重金属镍的处理问题,在实现菌糠资源化利用的基础上,验证了其在重金属镍的水污染处理方面具有较广阔的应用前景。

Abstract:

In order to explore the treatment of heavy metal nickel and the excessive waste of bran resources, this study used Pleurotus eryngii mushroom bran, agaricus mushroom bran and shiitake mushroom bran as raw materials to prepare biochar (PEBC, PGBC and LEBC), and scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and surface area measurement (BET) were applied to characterize their structure. Zeta potential was determined to explore the adsorption mechanism, and the adsorption effect of three kinds of bran biochar on nickel was compared by adsorption experiments. The results showed that all three kinds of bran biochar had irregular pores and more mineral crystals attached to the surface. In general, PEBC had the best adsorption effect with a removal rate of more than 99% and the maximum equilibrium adsorption capacity reaching 122.89 mg/g. In this study, waste bran was used to explore the treatment of heavy metal nickel, which proved that it had a broad application prospect in the treatment of heavy metal nickel in water pollution based on the resource utilization of bran.
