An Experimental Study of the Loading and Controlled Release of Salicylic Acid on Zeolite Nanocomposite

The encapsulation potential of salicylic acid on the zeolite as porous material was studied. The produced composite is working as drug delivery carrier in which the zeolite is a host and the salicylic acid is a guest. Characterization with XRD and FTIR techniques demonstrated the successful loading of salicylic acid into the zeolite nanoparticles. Loading of salicylic acid on the zeolite at 25 oC was 18%. The drug release of salicylic acid in water at pH 7 and 37 ºC was achieved to obtain the kinetic data. The kinetic data was modeled to determine the release patterns of the drug delivery system
