Abstract

Background and objectives:  The presence of pharmaceuticals in the environment is an emerging concern in the environmental community. Sorption interactions of three high �C use antibiotics [Cefotaxime (CEF), Ciprofloxacin (CIP), and Oxytetracycline (OTC)] with soils from Erbil governorate were investigated. This study was aimed to find out the fate and the behavior of antibiotics in our local environment, no such study has been done in Kurdistan.

Methods: Adsorption of the selected antibiotics on the studied soil samples were conducted using batch equilibrium techniques. The samples were analyzed by HPLC and UV visible spectrophotometer.

Results: Adsorption data were correlated with linear distribution, Freundlich and Langmuir models. Freundlich model being found to provide the best fit of the experimental data (R2 ��0.856). The results showed that the three studied antibiotics were found to adsorb strongly to the soils with 50- 76% adsorbed under all experimental conditions. Values of equilibrium constant were increased with temperature. Values of standard Free energy change were in the range -10.412 to -2.089, -14.102 to -2.721, and -25.952 to - 1.414 KJmol-1, for CEF, CIP and OTC respectively. Values of standard enthalpy change followed the range 51.043-74.081, 38.535-85.476, and 52.561- 73.512 Kjmol-1, for Cef, Cip and OTC respectively.

Conclusions: Values of standard Free energy change were negative and increased with temperature, indicating that at all experimental temperatures: the interactions of antibiotics with soils were spontaneous with a high preference of the soil surface and the adsorption occurred through a bonding mechanism. The results of effect of temperature and thermodynamic parameters confirm the adsorption process to be endothermic in nature.
