Abstract
NaX zeolite was modified with copper ions and used for the adsorption of mercaptobenzothiazole (MBT) from aqueous solution. Characterization studies by XRD, DTA/TGA and SEM/EDX confirmed the successful ion exchange and the retention of the zeolite's crystalline structure. XRD results show that the most intense peaks characteristic of 13X persist after the exchange reaction for all samples, with crystallinity ranging from 81 % for the Cu(27)X zeolite to 38 % for the Cu(88)X sample. All exchanged zeolites exhibited optimal MBT adsorption at pH= 6, with adsorption increasing with temperature. It is 195.3 mg/g for the best adsorbent. FTIR and XRD analyses revealed that the adsorption mechanism involves a strong chemical interaction between the nitrogen atom of MBT and the copper ions within the zeolite framework.
