摘要
研究了钙蒙脱土从 p H9.6的碳酸钠 -碳酸氢钠缓冲溶液中对月桂酸钠的吸附。 30℃和 2 5℃时得到双平台型吸附等温线 ,35℃时得到的吸附等温线显示三个吸附平台。根据两阶段吸附理论计算了吸附特性参数和吸附热力学参数 ,并对结果进行解释。
The adsorption of sodium laurate on calcium montmorilonite from the aqueous solution of Na 2CO 3 NaHCO 3(pH9.6)at various temperatures was investigated.The adsorption isotherms of LS type were obtained in the system at 25 and 30℃,while an isotherm of three plateaus obtained at 35℃.According to the two steps adsorption model and the general adsorption isotherm equation [6] ,the specific parameters for adsorption and adsorption thermodyamic parameters were calculated.Explanation on the mechanism of adsorption in the system was provided also.
