| 摘 要： | 利用掺杂稳定固定剂的沉积物样品进行cu、zn的热力学吸附，考察铁氧化物类、有机质类、黏土矿物类及磷酸盐类等11种物质的掺杂对沉积物样品吸附cu、zn热力学特征的影响。结果表明，所选用的掺杂材料中羟基磷灰石和磷酸氢二铵可同时提高沉积物吸附cu、zn的能力，其中Cu的最大吸附量提高70％～130％，Zn的最大吸附量提高150％以上，说明羟基磷灰石和磷酸氢二铵可望用作污染沉积物中重金属Cu、Zn的稳定固定剂。

| Abstract: | Thermodynamics adsorption of Cu and Zn on surfacail sediments was investigated after spiked with 11 kinds of stabilitating and immobilizing materials,including Fe oxides,organic materials,clay minerals,and phosphate minerals.The results showed that both Cu and Zn adsorption on surficial sediments could be improved with the addition of hydroxyapatite and diammonium hydrogen phosphate,with increase in the maximum adsorption of Cu and Zn by 70%-130% and above 150%,respectively,indicating that hydroxyapatite an... |
