摘    要:研究了硫酸亚铁改性沸石对钒(Ⅴ)吸附行为。详细探讨了溶液pH值、改性沸石投放量、吸附平衡时间和温度对水中钒(Ⅴ)吸附率的影响,并探讨了硫酸亚铁改性沸石吸附钒的机理。实验结果表明,pH=2.63,改性沸石投放量为0.5g,吸附时间为24h的条件下,处理初始浓度为50.0mg.L^-1的钒(Ⅴ)溶液100mL,去除率可达92%以上。吸附平衡符合Freundlich方程,室温(298K)时吸附容量为8.51mg.g^-1。

关 键 词:废水处理  含钒废水  改性沸石  吸附

Abstract:The adsorption of V (V) on zeolite modified by ferrous sulphate was studied. Some affecting factors, such as pH of the solutions, the adding amount of the modified zeolite, the adsorption time and temperature on the adsorption rate of V ( V ) ions was studied in detail, and the mechanism of V ( V ) adsorption onto the modified zeolite was discussed. The results showed that the removal ratio for V( V ) was about 92% for the treatment of 100 ml of 50.0 mg · L^-1 V( V ) by using 0.5g modified zeolite at pH 2.63 for 24 hours. The adsorption of V ( V ) on the modified zeolite could be described by the Freundlieh adsorption isotherm, and the adsorption capacity of V ( V ) on modified zeolite was 8.51mg · g^-1 at room temperature (298K).
Keywords:wastewater treatment  vanadium contamination  modified zeolite  adsorption
