摘要
以亚甲基蓝为吸附质,采用粉煤灰对其液相吸附,研究粉煤灰对亚甲基蓝的吸附模式.通过分光光度法跟踪吸附过程浓度变化,计算相关条件下的吸附量,分别对Freund lich方程和Langmu ir方程进行拟合,实验证明粉煤灰对亚甲基蓝的吸附较好地服从Langmu ir吸附模式.在此基础上对相关影响因素进行了实验研究,为粉煤灰处理印染废水提供了理论依据和实践依据.
In this paper, fly ash is used to absorb the organic dye - methylene blue from solution. And the authors put forward the adsorption isotherm that conforms to Langrnuir theory. The authors also study influence factors of the absorption by experiment. These results lay a foundation for treatment of printing and dyeing wastewater.
