Abstract:On the basis of the OECD Guideline 106, batch adsorption methods were employed to reveal the adsorption and desorption process of three tetracycline antibiotics in petroleum-contaminated soils. The Freundlich model was the best isotherm to describe all experimental data of adsorption and desorption (P tetracycline (2.975 and 2.771) > oxytetracycline (2.340 and 2.337). The dominant mechanism of three tetracycline antibiotics adsorption was physical adsorption in petroleum-contaminated soils. HI was in the order of oxytetracycline > tetracycline > chlortetracycline with significant difference (P<0.01). For same antibiotic, the petroleum-contaminated extent could not affect the adsorption and desorption of three antibiotics in soil. Thus soil pollution would be greatly increased and complicated with the antibiotic occurring in petroleum-contaminated soils.
