研究了钙基累托石去除废水中Pb（II）的各种环境因素，包括接触时间、pH、离子强度、固含量、共存离子、腐殖酸（HA）和温度。Pb（II）在钙基累托石上的吸附动力学符合准二级动力学模型。吸附过程强烈依赖于pH值和离子强度。结果表明，HA和共存离子的存在对Pb（II）在钙基累托石上的吸附有明显的影响。此外，采用Langmuir和Freundlich模型对吸附等温线进行了模拟。热力学参数表明吸附过程是自发的吸热过程。由此可见，钙基累托石具有良好的处理铅污染废水的潜力。
The removal of Pb(II) from wastewater by Ca-rectorite was investigated as various environmental factors containing contact time, pH, ionic strength, solid content, coexisting ions, humic acid (HA), and temperature. The kinetic sorption of Pb(II) on Ca-rectorite was well described by the pseudo second-order model. The sorption process was strongly dependent on pH and ionic strength. The results indicated that the presence of HA and coexisting ions influenced the sorption of Pb(II) on Ca-rectorite obviously. Besides, the Langmuir and Freundlich models were employed to simulate the sorption isotherms. The thermodynamic parameters indicated that the sorption process was spontaneous and endothermic. It is possible to conclude that Ca-rectorite has a good potential for disposal of lead-contaminated wastewater.
