摘要:
为探究水合二氧化钛对亚铁离子的吸附平衡与吸附动力学,通过静态吸附实验，研究了吸附平衡时间、亚铁离子浓度、吸附硫酸质量浓度和温度对水合二氧化钛吸附亚铁离子的影响；通过真空抽滤洗涤实验考察了洗水硫酸质量浓度和温度对洗涤过程中铁去除率的影响.结果表明，水合二氧化钛吸附亚铁离子的平衡吸附时间为9 h，亚铁离子初始浓度最佳为300 mg/L, 硫酸质量浓度的增加和温度的升高均不利于水合二氧化钛对亚铁离子的吸附；吸附动力学符合一级动力学 Lagergren 方程，吸附等温方程符合Freundlich方程；洗涤过程中洗水的温度升高和洗水的硫酸质量浓度提高均利于亚铁离子的去除.
Abstract:
To explore the hydrated titania on ferrous ions adsorption equilibrium and adsorption kinetics, the effect of the adsorption equilibrium time, initial concentration of ferrous ions, acidity and temperature on hydrated titanium dioxide adsorbing ferrous ion was studied by the static adsorption experiment and suction filter washing experiment. Meanwhile, the effect of acidity and temperature of washing water on iron removal rate in the washing process was also studied. The results indicated that the adsorption equilibrium time of hydrated titanium dioxide adsorbing ferrous ions is 9 hours, and the best of initial concentration of ferrous ions is 300 mg/L; the adsorption kinetics accords with first order kinetics equation of Lagergren, and the adsorption isotherm equation accords with Freundlich equation; the increasing of temperature and acidity is unfavorable for hydrated titanium dioxide adsorbing ferrous ions; increasing the temperature and acidity of washing water in the washing process increases the iron removal rate.
