| 摘 要： | 为了探索萘在松花江沉积物上的吸附-解吸特性,采用实验室模拟方法进行研究.结果表明:萘在沉积物上的吸附在8 h内可以充分达到平衡,吸附过程表现出一定的非线性,与Linear和Langmuir方程相比,Freundlich方程能够较好地拟合萘的吸附和解吸过程,拟合度分别为0.93和0.962.萘的解吸行为存在较为明显的滞后现象,随水体中平衡浓度升高,萘的迟滞系数降低.

| Abstract: | To study the adsorption and desorption behavior of naphthalene on the sediment of Songhua River,the simulation method was adopted.Results show that the adsorption of naphthalene can reach the dynamic equilibrium adequately in 8h,and the adsorption procedure presents somewhat nonlinearity.The adsorption and desorption isotherm curves of naphthalene can be well described by Freundlich equation,and the goodness-of-fit is 0.93 and 0.962 respectively.Desorption of naphthalene is observed with an obvious hysteresis,and the hysteresis index decreases with the increase of equilibrium concentration. |
