【摘要】 对苯甲酸在土壤中的吸附特征进行了研究,观察了pH值和离子强度等因素对吸附的影响.结果表明,苯甲酸的吸附过程符合一级动力学规律和Langmuir等温式;pH值降低或离子强度增加使苯甲酸在土壤中的吸附程度明显减小.更多还原

【Abstract】 The adsorption characteristics of phenylformic acid on soil was studied.It was investigated that the influence of some factors, such as pH value and ionic strength on the adsorption. First order kinetics mode and Langmuir isotherm was suggested as the most appropriate type for the adsorption of phenylformic acid. The reduction of pH figure or the rise of the ionic strength can make the adsorption weaken.更多还原
