摘要:
采用恒温批处理平衡法研究生物炭热解温度、吸附剂质量、吸附质溶液初始pH值对锰改性玉米秸秆生物炭吸附1,4-苯醌的影响,并进行了动力学和热力学分析。经MnSO4改性的玉米秸秆生物炭明显提高了对1,4-苯醌的吸附去除能力,同时热解温度的升高能大幅度提高其吸附能力,当吸附剂质量为20 mg时,1,4-苯醌的吸附量和去除率为最佳值。pH=8.0时吸附量最高,达到75.977 mg/g。准二级动力学模型能够更好地描述该吸附过程,其控制步骤为化学吸附。等温吸附试验结果表明,锰改性玉米秸秆生物炭吸附1,4-苯醌的机理主要以多分子层吸附为主,伴随表面单分子层吸附。
Abstract:
The effects of pyrolyzation temperatures,absorbent mass and the original solution pH on the adsorption of 1,4-benzoquinone by Mn-modified cornstalk biochar were studied, and adsorption kinetics and isotherms were analyzed as well. The modification by MnSO4 obviously improved the adsorption performance of cornstalk biochar, and an increase in the pyrolytic temperature enhanced the removal performance as well. The biochar presented the highest adsorption capability and removal rate at 20 mg of dosage. The adsorption capacity at pH=8.0 of absorbate solution was the highest, reaching 75.977 mg/g.The pseudo-second order kinetic model fit the kinetics better, indicating a chemisorption process during the adsorption. Isotherm study demonstrated a dominant multi-molecular layer adsorption accompanied by a monomolecular layer adsorption.
