Abstract
Amprolium is one of the veterinary pharmaceuticals that has been widely used as antibacterial agents and as a growth promoter in livestock, it can produce chronic adverse actions that could affect many organisms and humans. In this study, Salvadora persica stem ash and roots were used as biosorbent for the removal of Amprolium hydrochloride (AMP) from aqueous systems. The effect of different parameters such as the initial concentration of AMP, pH, contact time, and adsorbent dosage were investigated. Maximum removal efficiency reached 98% and 96% for S. persica roots and seeds ash, respectively at pH = 7 and contact time of 40 min. Isothermal studies indicated that the AMP removal correlates more with the Freundlich isotherm model. S. persica roots exhibit better removal efficiency than S. persica seeds ash under all the studied parameters. This study shows that S. persica is efficient in removing AMP from water.
