Study on the Adsorption Properties of Amphoteric Pyrolytic Carbon for 3-Hydroxybenzoic Acid in Water
摘要: 本研究在热解炭表面接枝间苯二胺和烯丙基磺酸钠制得两性热解炭，采用静态吸附实验和吸附动力学实验对水中3-羟基甲苯的吸附行为进行研究，并用吸附热力学和吸附动力学来探讨用两性热解炭吸附3-羟基苯甲酸的机理。结果表明：3-羟基苯甲酸用两性热解炭来吸附表现出良好的吸附性能。通过对模型的拟合便于分析吸附剂的吸附特征，采用Langmuir方程，该过程属于化学吸附，热力学参数计算结果表明，吸附3-羟基苯甲酸的焓变(∆H)为17.13 kJ/mol，熵变(∆S)为73.47 J/(mol∙K)。
Abstract: In this study, amphoteric pyrocarbon was prepared by grafting m-phenylenediamine and sodium allyl sulfonate on the surface of pyrocarbon. The adsorption behavior of 3-hydroxybenzoic acid in water was studied through static adsorption experiment and adsorption kinetics experiment. The adsorption mechanism of 3-hydroxybenzoic acid by amphoteric pyrocarbon was discussed by adsorption thermodynamics and adsorption kinetics. The adsorption performance of 3-hydroxybenzoic acid by amphoteric pyrolytic carbon is good. Langmuir equation can be used to better fit the adsorption of 3-hydroxybenzoic acid in water by amphoteric pyrocarbon, which belongs to chemical adsorption. The calculation results of thermodynamic parameters show that the enthalpy change (Δh) of adsorption of 3-hydroxybenzoic acid is 17.13 kJ/mol, and the entropy change (Δs) is 73.47 J/(mol K).
