摘要
采用聚氯化铝压滤残渣(PACR)改性制备新型吸附剂(M-PACR),考察该吸附剂对亚甲基蓝的吸附效果及脱色性能。SEM表明:M-PACR较PACR表面孔隙结构更加明显;BET分析数据显示:M-PACR较PACR比表面积增大了近3倍;吸附实验结果表明:M-PACR的最佳吸附pH为8。M-PACR对亚甲基蓝的吸附符合二级吸附动力学模型与Langmuir等温吸附模型。
A new type of adsorbent (M-PACR) was prepared by modified polyaluminum chloride residue (PACR). The adsorption properties of adsorbent to methylene blue were investigated. SEM showed that the surface pore structure of M-PACR was more obvious than PACR. BET data showed that the specific surface area of M-PACR was nearly three times larger than that of PACR. The adsorption experimental results showed that the optimum adsorption pH of M-PACR was 8. The adsorption of methylene blue by M-PACR conformed to the second-order adsorption kinetics and Langmuir isothermal adsorption model.
