The Adsorption of Oxytetracycline in the Petroleum-Contaminated Soils

摘要：

　　On the basis of the OECD Guideline 106,we employed batch adsorption methods to study the adsorption process of oxytetracycline(OTC) in petroleum-contaminated soils.The Langmiur model was the best isotherm to discribe all experimental data (P<0.01).The data obtained in this present study indicates that the petroleum in soils can greatly affect the adsorption of OTC depends on the content of petroleum.The presence of petroleum may regulate the fates of OTC considerably,which should be taken into consideration while modeling their fate in the environment as well as defining their bioavailability and environmental risks.Petroleum in soils can affect OTC sorption in two ways:one way,when the content of petroleum is lower,it facilitied to the adsorption of OTC in soils,but when the content is overloaded,it can compete with OTC for the adsorption sites.In the adsorption of OTC in soils with different particle size,we can find that small particled soil have greater adsorption capacity.It can be explained by the greater surface area of small particles.Soil pollution would be greatly increased and complicated with the antibiotic occurring in pertroleum-contaminated soils.
