    Experiments of Factors Influencing Adsorption of As (V) in Water by Granite Red Soil

    • 摘要: 为探讨花岗岩母质红壤吸附水中砷(Ⅴ)的效果和机理, 采用静态吸附实验, 研究溶液砷初始浓度、反应时间、温度、pH值等因素对红壤吸附水中砷的影响.当溶液砷初始浓度小于5.0 mg/L时, 红壤对砷的去除率均大于97%;随着砷初始浓度增大, 去除率逐渐降低; 反应初期(0~120 min), 红壤对砷的去除率迅速增大至95.0%左右.此后, 去除率缓慢增大, 直到720 min后, 去除率达到97.0%左右, 并趋于稳定; 在砷初始浓度一定时, 红壤对砷的吸附量随着温度的升高逐渐增加, 但增加幅度较小; 红壤对砷的去除率随着体系pH值的增大呈减小趋势; 正交试验表明, 在砷初始浓度为5.0 mg·L-1、反应时间为120 min、pH为5.0及反应温度为40℃的组合下, 红壤对砷的去除率最大.
