  • 摘要: 针对水体中日益突出的重金属与有机物污染问题，本文通过KOH活化法制备了高吸附性能的芦苇基生物炭材料，通过考察pH、离子强度、吸附时间、污染物浓度等影响因素，研究芦苇生物炭对铜离子（Cu2+）和双酚A（BPA）两种无机-有机污染物的吸附性能，并分析吸附机理.实验结果表明，活化生物炭内部结构疏松、多孔，BET比表面积最高达965.31 m2·g-1，平均孔径在3 nm左右；生物炭表面富含-OH、-COOH等含氧官能团，电离子后使生物炭表面带有负电荷.芦苇生物炭吸附铜离子以静电作用力为主，溶液pH、离子强度等因素对于吸附过程有较大影响，且中性条件和低离子强度利于铜离子的吸附.分子形态的BPA依靠π-π共轭作用、范德华力以及氢键等作用力吸附于生物炭表面，酸性和中性pH的变化对BPA吸附的影响很小；碱性条件下，由于发生电离作用，BPA的吸附容量呈现下降的趋势.通过分析可知，吸附过程更符合准二级动力学和Freundlich吸附等温方程，表明生物炭对两种污染物的吸附以化学吸附为主，并且是多分子层吸附.
    Abstract: Considering the increasingly prominent problem of heavy metals and organic pollutants pollution in water, in this study, the reed-based biochar material with high adsorption capacity was prepared by KOH activation method. We investigated the adsorption performance and analyzed adsorption mechanism of reed-based biochar with respect to two inorganic and organic pollutants, copper ion (Cu2+) and bisphenol A (BPA). The impact factors, such as pH, ionic strength, adsorption time, pollutant concentration, were investigated. The experimental results suggested that the internal structure of activated biochar was loose and porous, and the specific surface area of BET reached 965.31 m2·g-1 with an average pore size of approximately 3 nm. The biochar surface contains rich oxygen-containing functional groups, such as hydroxyl (-OH) and carboxyl (-COOH) groups, it was electronegative after ionization of oxygen-containing functional groups. The adsorption of copper ions by reed-based biochar was dominated by electrostatic force, therefore the factors such as solution pH and ionic strength showed great influence on the adsorption, and the neutral conditions as well as low ionic strength were favorable for the adsorption. The BPA in molecular form was adsorbed on biochar surface depending on π-π conjugation, van der Waals force, and hydrogen bond, thus the change of acidic and neutral pH had few effects on the adsorption of BPA. Under alkaline conditions, the adsorption capacity of BPA decreased due to ionization. It could be found through analysis, the adsorption process accorded with pseudo-second-order kinetics and Freundlich adsorption isotherm equation. It indicated that the adsorption of two pollutants by biochar was dominated by chemical adsorption, which was multilayer adsorption.
