中文摘要：
通过室内实验,分析了悬浮物对0号柴油乳化油吸附、解吸的基本规律,并对泥沙浓度和温度因素影响进行了研究。实验结果表明,悬浮物对0号柴油的吸附和解吸过程符合一级动力学过程;悬浮物的平衡吸附量随着液相平衡浓度的升高而趋于平缓,Langmuir方程和Freundlich方程都能较好的反映珠江广州段泥沙的吸附规律;固相平衡吸附浓度随着悬浮物浓度的升高而降低,而液相解吸平衡浓度则随着悬浮物浓度的升高而增加;此外,温度的升高不利于柴油吸附过程而更有利于解吸过程。
英文摘要：
Based on experimental analysis,the characteristics of adsorption and desorption of 0# diesel oil by suspended substance from Pearl River were investigated along with the substance concentration and temperature effects.The results showed that the dynamics of the both adsorption and desorption could be illustrated by a first-order dynamic formulation;the equilibrium adsorption of suspended substance tended to deaccelerate as the aqueous equilibrium concentration increased.Both Langmuir and Freundelich formulation could fairly interpret the isotherm of adsorption process by suspended substance of Pearl River.The equilibrium adsorption concentration and the desorption of suspended particles decreased while the suspended substance concentration increased,meanwhile temperature increase was more likely to accelerate desorption and hinder adsorption process.
