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 Na-laurate on calcium montmorillonite from pH9.6 sodium carbonate-sodium bicarbonate buffer solution was studied. Two-plate adsorption isotherm was obtained at 30 ℃ and 25 ℃, and the adsorption isotherm at 35 ℃ showed three adsorption platforms. According to the two-stage adsorption theory, the adsorption and adsorption thermodynamic parameters were calculated and the results were explained.
