Abstract

|
|
|
Adsorption characteristics of triadimefon and diniconazole(pesticide) by natural zeolite() and several synthetic zeolites were Investigated. The synthetic zeolites used En this study were as follows: Faujasite synthesized from coal fly ash(); Zeolite synthesized from the mixture of FAU and Na-Pl synthesized from the ratio of Cheju scoria 6 to coal fly ash 4 by weight(); waste fluid catalytic cracking catalyst(). The distribution coefficient, and Freundlich constant, decreased in the fellowing sequence : among the zeolites. The distribution coefficient and the adsorption capacity of for pesticides were 4.4 and 2.6 times higher for triamefon, and 2.0 and 2.4 times higher for diniconazole than those of , respectively.
