摘要

为了提高甘蔗渣对直接红81的吸附能力，采用棕榈酸、硬脂酸、油酸和丙酸四种酸对甘蔗渣进行处理。考察了pH、吸附剂用量、初始染料浓度和接触时间等实验变量对吸附效果的影响。染料吸附动力学符合拟二级动力学模型，符合Langmiur方程。

Acid pretreated bagasse as a suitable biosorbent for direct red 81 removal

In order to enhance the sorption capacity of bagasse on direct red 81, it was treated with four acids, namely palmitic, stearic, oleic and propionic acids. The effects of various experimental variables pH, sorbent dose, initial dye concentration and contact time were investigated. The kinetics of dye adsorption fit well with the pseudo-second-order kinetic model and it obeys the Langmiur equation.
