| 摘 要： | 从吸附反应动力学方程和质量守恒方程出发,导得室内静态试验中泥沙吸附量和水相重金属浓度随时间变化的计算公式,并得出泥沙平衡吸附量和水相平衡浓度随泥沙吸附特性、水相重金属离子初始浓度和泥沙浓度变化的计算公式。结合室内试验,认为泥沙浓度不影响吸附特性参数,如饱和吸附量b、吸附-解吸速率常数k及吸附速率系数k1.

| Abstract: | Based nn adsorption dynamic equation and mass conservation equation, the variation of sediment adsorption of heavy metal ion with time and that of heavy metal ion concentration with time have been deduced. Furthermore, formulas for calculating the equilibrium sediment adsorption of heavy metal ion and the equilibrium concentration of heavy metal ion in water phase have been established too. And based on proceeding fact the following conclusion is deduced: sediment concentration does not effect sediment adsorption behaviour, namely, saturated adsorption content, coefficient of adsorption rate and coefficient of desorption rate. |
