Abstract

Removal of lead from aqueous solutions was studied using nanocomposite absorbent of bentonite/-alumina. The novel absorbent was characterized using XRD, FT-IR and SEM-EDX. Absorption process optimization using response surface methodology (RSM) and experimental design was performed with central composite design technique. The effects of Pb(II) initial concentration, adsorbent dosage, and composite percentage on Pb(II) removal percentage and adsorption capacity were examined. The adsorption capacity of 166.559 mg/g and removal % of 82.9887 with desirability equal to 0.763 were obtained for optimal initial concentration of 200 mg•l-1, adsorbent dosage of 0.5 mg•l-1, and composite percentage of 7.08 % determined using RSM design. The equilibrium adsorption data were investigated by Langmuir, Freundlich and Dubinin-Radushkevich isotherm models. It was found that Freundlich isotherm model fits better compared with other models.

伊斯法罕膨润土- γ-氧化铝陶粒去除水溶液中铅(II)的研究
研究了膨润土/-氧化铝纳米复合吸附剂对铅的去除效果。采用XRD、FT-IR和SEM-EDX对新型吸附剂进行了表征。采用响应面法优化吸收工艺,采用中心复合设计技术进行试验设计。考察了Pb(II)初始浓度、吸附剂投加量和复合配比对Pb(II)去除率和吸附量的影响。采用RSM设计确定最佳初始浓度为200 mg•l-1,吸附剂用量为0.5 mg•l-1,复合率为7.08%时,吸附量为166.559 mg/g,去除率为82.9887,理想度为0.763。采用Langmuir、Freundlich和Dubinin-Radushkevich等温线模型研究了平衡吸附数据。结果表明,Freundlich等温线模型拟合效果较好。
