摘要

研究了香蕉皮和蔗渣粉对Eurozol海军蓝(ENB)活性染料的吸附性能。考察了pH、接触时间、搅拌速度、温度、初始染料浓度、吸附剂用量等参数对染料吸附效率的影响。香蕉皮和甘蔗渣对ENB染料的吸附去除率分别为72%和70%。同时添加两种生物吸附剂可去除68%的染料。发现Langmuir等温线模型适合ENB染料在香蕉皮和蔗渣粉上的吸附。香蕉皮粉、蔗渣粉和混合吸附剂的最大吸附量分别为24.09、32.46和27.54 mg/g。

Removal of reactive dye from aqueous solutions using banana peel and sugarcane bagasse as biosorbents

The adsorption of Eurozol Navy Blue (ENB) reactive dye was examined using banana peel and sugarcane bagasse powders. Several parameters such as pH, contact time, agitation speed, temperature, initial dye concentration, and adsorbent dosage were considered and their impact on dye adsorption efficiency was evaluated. The removal percentages of ENB dye due to adsorption on banana peel and sugarcane bagasse were 72% and 70%, respectively. Simultaneous dosing of both biosorbents resulted in 68% dye removal. The Langmuir isotherm model was found to fit the adsorption of ENB dye on banana peel and sugarcane bagasse powders. The corresponding maximum adsorption capacities were equal to 24.09, 32.46, and 27.54 mg/g for banana peel powder, sugarcane bagasse powder, and the mixture of adsorbents, respectively.
