Abstract

Zeolites are crystalline and hydrated aluminosilicates from earth alkali and alkaline metals, which are used for the removal and separation of Pharmaceutical, colored, and metallic pollutants due to their chemical structure and proper surface area. In the present study, first, natural Zeolite was powdered by ball mill, and after that, it was modified by a cationic surfactant of the cetyltrimethylammonium bromide. The modified Zeolite was investigated by XRF, FTIR, SEM, BET, and XRD techniques, which is based on the BET test, The specific surface area, mean pore diameter, and total volume cavities of Zeolite were 11. 931 m2/g, 31. 546 nm, and 0. 0941 cm3/g, respectively. Additionally, the efficiency of the sample was studied for removal of Amoxicillin from the aqueous medium. The results showed that environmental factors such as Adsorbent dose, contact time, pH, Temperature, and Amoxicillin concentration were effective in removal percentage. In addition, the experimental data of the amoxicillin-Adsorption process better matched with the isothermal model of Ferndlich as well as kinetic of the pseudo-second order. According to the Freundlich model, Adsorption capacity of amoxicillin with the adsorbent dosage 2 g/l, contact time of 180 min, pH=9, and initial concentration of 120 ppm was 37. 3 mg/g.
