针铁矿和针铁矿—胡敏酸复合体对Se(Ⅳ)吸附机制
针铁矿 针铁矿—胡敏酸复合体 等温吸附 硒(Ⅳ) X—射线光电子能谱(XPS)
2018/4/28
研究了针铁矿和针铁矿—胡敏酸复合体对Se(Ⅳ)的吸附机制。结果表明:针铁矿和复合体对Se(Ⅳ)的最大吸附容量分别为0.202 mmol g-1和0.159 mmol g-1。针铁矿的等温吸附数据适合用Langmuir模型拟合,而Freundlich模型更适合描述复合体的等温吸附过程。针铁矿的等电点(IEP)在7.0附近,复合体的IEP<3.0;当pH=4.0时,它们的表面电位分别为46.6 mV和...
通过慢速滴定法合成了高活性的多羟基结构亚铁FHC(Cl-),对FHC(Cl-)去除Se(Ⅳ)的动力学进行了研究,并对体系中的投加量、pH值、溶解氧和氯化钠浓度进行了响应面分析.研究结果表明,FHC(Cl-)去除Se(Ⅳ)的表观速率常数kobs=0.60 min-1,约为纳米零价铁的4倍和零价铁的16倍.由Box-Benhnken设计拟合得出响应值对编码自变量的二次多项回归方程为Y(c/c0)=0....
