Background: In recent years, has been created many concerns about the entry of antibiotics in aquatic environments. The aim of this study is to Investigation of The effect common ions in water sources to remove cephalexin using absorbent mineral pumice (pumice).
Materials and Methods: This study was Foundation – Applied. In the first stage, absorbent properties were determined using techniques (XRD, BET, XRF, FTIR and SEM) before and after absorption And then, in the second stage, Performance of pumice by changing variables such as time, PH, concentration of pumice, concentrations of cephalexin, different concentrations of calcium, magnesium, copper, sulphate, and carbonate were studied.
Results: The results showed that pumice has a high efficiency in the absorption of cephalexin from aqueous solutions. For cephalexin, maximum efficiency in the contact time of 150 minutes, PH = 5, adsorbent dose of 5 g/l, concentrations of antibiotics 10 mg/l was observed respectively 44.75% (using raw pumice) and 55.66% (using modified pumice).
Conclusion: According to the results obtained with increasing adsorbent dosage and the contact time efficiency increased. When PH and concentrations of cephalexin are increased efficiency is reduced. In this study, the modified pumice with hydrochloric acid in comparison with raw pumice has better efficiency in the absorption of cephalexin. According to the results of this study ions had little effect on the absorption of cephalexin. In this study, adsorption Cephalexin on to pumice follow of Frondlykh isotherm and pseudo-second order.
Keywords: Absorption, pumice, cephalexin, cations, anions
