Abstract

Salt occlusion in zeolite is a unique phenomenon that takes place only when the salt size is similar to the window size of host zeolite. KClO3-occluded zeolite, as an environment-friendly oxidant, has a high potential for effective removal of various organic pollutants. This study was carried to investigate the characteristics and the removal kinetics of fungicide chlorothalonil by zeolite-KClO3 complex. About 10% of KClO3 was occluded in zeolite pores synthesized by salt-thermal method from fly ash, although the occlusion amount was relatively less compared to that of nitrate salts. By occlusion with KClO3, no remarkable changes were found in X-ray diffraction patterns of cancrinite, whereas some decrease of overall peak inten- sities was found with those of sodalite. Different releasing kinetics of ClO3- ion were observed in distilled water and soil solution from zeolite-KClO3 complex. Two reactions, hydration and diffusion, seem to be related with the release of KClO3. Therefore, the release isotherm of ClO3- ion well fitted to the power function model which indicate the release was made by hydration and diffusion. The removal of chloro- thalonil by zeolite and KClO3 reached at reaction equilibrium within 6 hours by 18% and 47%, respectively. However, the chlorothalonil removal by the zeolite-KClO3 complex increased slowly and steadily up to 92% in 96 hours. These findings suggested that zeolite-KClO3 complex could be applied for effective removal of organic contaminants in the soil and aqueous environment.
