| 摘 要： | 研究了双酚A在松花江水体沉积物上的吸附特性．实验结果表明：在酸性条件下底泥对双酚A的吸附量随着溶液pH值的升高而降低，在碱性条件下影响不明显；沉积物对双酚A的吸附量随着沉积物粒径的增大而降低，随着沉积物量的增大而增大；沉积物有机质对双酚A的吸附作用在溶质的整个溶解度范围内，吸附等温线都是线性的．入江口沉积物和九站沉积物对双酚A的吸附等温线均符合Langmuir方程，白旗采样点沉积物对双酚A的吸附等温线符合Freundlich方程． |

| Abstract: | The sorption characteristics of bisphenol A on sediments in Songhua River were studied.The results show that with the increase of pH value in the acidic condition,the absorption of bisphenol A to sediment decreases,but in the alkaline condition,the influence is not obvious.And with the increase of the sediment size,the absorption of bisphenol A to sediment decreases,and with the increase of the sediment amount,it increases.For the sediment organic matter,adsorption isotherm are linear within the solubility.The adsorption isotherms of bisphenol A fits the Langmuir Equation on sediment of the river's entrance and Jiuzhan,and the adsorption isotherms of bisphenol A fits Freundlich Equation on sediment of Baiqi. |
