The adsorptive removal of boron from aqueous solution by using the neutralized red mud was studied in batch equilibration technique. The effects of pH, adsorbent dosage, initial boron concentration and contact time on the adsorption were investigated. The experiments demonstrated that boron removal was of a little fluctuation in pH range of 2-7 and it takes 20 min to attain equilibrium. The adsorption data was analyzed using the Langmuir and the Freundlich isotherm models and it was found that the Freundlich isotherm model represented the measured sorption data well.
采用分批平衡技术研究了用中和赤泥从水溶液中吸附去除硼的过程。考察了pH值、吸附剂用量、初始硼浓度和接触时间对吸附的影响。实验表明,在pH值为2 - 7的范围内,硼的去除率有轻微波动,达到平衡需要20分钟。用Langmuir和Freundlich等温线模型对吸附数据进行了分析,发现Freundlich等温线模型能很好地描述实测的吸附数据。
