The adsorption of dye acid mordant brown RH followed both the Freundlich and Langmuir isotherm models. 酸性媒介棕RH的吸附既符合Freundlich方程,也可用Langmuir吸附等温方程描述。
Adsorption of Direct Dark Brown M and Acid Mordant Brown RH dyes in water by dried activated sludge, pyrolysis activated sludge and modified activated sludge, which made from the material of discarded activated sludge of municipal wastewater treatment plant, was studied. 以城市污水处理厂剩余活性污泥为原料,制取干污泥、热解污泥和改性污泥作为吸附剂,对直接深棕M和酸性媒介棕RH等染料进行了吸附试验研究。
