摘要
以松木层孔菌菌渣为原料制备生物炭,并将其应用于甲基橙水溶液的吸附。研究了生物炭用量、吸附温度、吸附时间和超声功率对松木层孔菌生物炭吸附性能的影响,并通过热重分析、比表面积及孔径分析和傅里叶红外光谱分析揭示了松木层孔菌生物炭吸附性能与其结构的关系。结果表明:在超声辅助作用下,生物炭用量对松木层孔菌生物炭吸附甲基橙效果的影响最大;氯化锌改性松木层孔菌生物炭吸附能力比未改性的要好,其主要原因是改性松木层孔菌生物炭因其多孔结构具有更大的比表面积,而且表面官能团种类和数量更加丰富。
A mushroom-based biochar was prepared from the residue of Phellinus pini and applied to the adsorption of methyl orange aqueous solution. The effect of biochar dosage,adsorption temperature,adsorption time and ultrasonic power on the adsorption property of the biochar was investigated. The relationship between the adsorption property of the biochar and its structure was revealed by thermogravimetric analysis,surface area and pore size analysis and Fourier infrared spectroscopy. The results showed that, under the aid of ultrasound, the effect of biochar dosage on the adsorption of methyl orange by the biochar was the greatest. Moreoverm,the adsorption capacity of the modified biochar through zinc chloride was better than that of the unmodified one,the main reason was that the modified biochar had a larger specific surface area because of its porous structure,and the surface functional groups were more abundant in species and quantity.
