摘要
研究水溶液中辛基酚聚氧乙烯醚在棉织物上的吸附行为。采用高相液相作为检测方法，探讨了极限吸附量与温度之间的关系。结果表明：可用准二阶动力学方程准确表征棉织物吸附辛基酚聚氧乙烯醚的动力学过程；辛基酚聚氧乙烯醚在棉织物上的吸附等温线较好地符合Langmuir-Freundlich方程；棉织物对辛基酚聚氧乙烯醚的极限吸附量与温度有一定的线性相关性，最大吸附量可超7mg／g。
The adsorption behavior of octylphenol ethoxylates on cotton fabric in aqueous solution was studied and the relation between extreme adsorption capacity and temperature was also discussed by using the detection method of HPLC.As shown in the result,the pseudo-second-order kinetic equation can be used to correctly represent the kinetic process of cotton fabric's absorption of octylphnol ethoxylates;the adsorption isotherm of octylphenol ethoxylates on cotton fabric well conforms to the Langmuir-Freundlich equation.In addition,there was a linear correlation between the cotton fabric's extreme adsorption capacity of octylphenol ethoxylates and temperature and the maximum absorption capacity can exceed 7mg/g.
