• 摘要：本文利用化学试剂逐级提取法测得颗粒物上各结合态吸附等温线,初步建立了沉积物和土壤对铜、镉离子吸附时包含pH和温度变量的各结合态的平衡模式,运用该模式对同类条件下的金属结合态分布及相对结合能力的变化进行了计算预测。

• Abstract：Adsorption isotherms have been determined of bonding species of heavy metals adsorbed on the particulates by making use of stagewise solvent-extraction method. Thus equilibrium model was established of pH and temperature variations for bonding species of copper and cadmium ions adsorbed on sediments and Soils. Calculation estimation can be predicted by employing this model in order to find out under the similar conditions distribution and relative bonding ability of the bonding species of the metals.
