摘要
研究了漆酚-水杨酸吸附Hg2+的动力学和热力学特性。结果表明,漆酚-水杨酸树脂对Hg2+的吸附符合Langmiur吸附模型,吸附等温线与Langmiur方程高度相关。在25℃,Langmiur吸附系数a=33.9,饱和吸附量Qm=264 mg.g-1。Langmiur吸附表观速率常数k=1.71 h-1。
The kinetic and thermodynamic characteristics of adsorption of urushiol-salicylic acid resin were systematically studied for Hg^2+. The thermodynamics showed that the adsorption isotherm could be described by the Langmuir equation. At the temperature of 25℃ ,the Langmuir adsorption coefficient and the saturation adsorption quantity were a=33. 9,Qm =264 mg ·g^-1 respectively. The kinetics indicated that the Langmuir apparent rate constant was k=1.71 h^-1.
