甘蔗渣粉煤灰是印度制糖业产生的一种废物，已被转化为一种廉价的吸附剂材料，用于去除罗丹明B和亚甲基蓝两种基本染料。结果包括pH、吸附剂剂量、染料浓度和表面活性剂的存在对罗丹明B和亚甲基蓝的去除率的影响。吸附数据已与Langmuir和Freundlich吸附模型相关联。得到的热力学参数表明了该工艺的可行性，动力学研究为脱除过程提供了必要的机理信息。
Bagasse fly ash, a waste generated in sugar industries in India, has been converted into an inexpensive adsorbent material and utilized for the removal of two basic dyes, rhodamine B and methylene blue. Results include the effect of pH, adsorbent dose, dye concentration, and presence of surfactant on the removal of rhodamine B and methylene blue. The adsorption data have been correlated with both Langmuir and Freundlich adsorption models. Thermodynamic parameters obtained indicate the feasibility of the process, and kinetic studies provided the necessary mechanistic information of the removal process.
