Adsorption of chlorotriazine herbicide onto unto unmodified and modified kaolinite: equilibrium, kinetic and thermodynamic studies, Egyptian Journal of Aquatic Research. 45: 99 -107.https://www.journals.elsevier.com/egyptian.journal-of-aquatic -research/http://hdl.handle.net/123456789/3530In the recent time, adsorption is a commonly economical way for removal of pollutants from wastewater. Chlorotriazine has been a serious threat to life of both human and animal. Modified kaolinite clays were separately prepared by chemical impregnation method with 2M H2SO4 and 2M NaOH respectively in w/ v of 1:2 for a period of 24h to give unmodified kaolinite (UKC), 2M H2SO4 modified kaolinite (2-AKC) and 2Mm3 NaOH modified kaolinite clays (2-BKC) respectively. The UKC with maximum intake value (125.3mg/g) was derived at equilibrium of 1100mg/L while 96.65mgg−1 of 2-AKC was obtained at equilibrium of 500mgL−1 and that of 2-BKC was found at equilibrium of 700mg/L. The Langmuir isotherm best explained the removal of Chlorotriazine onto various kaolinite clays while pseudo 2nd order kinetics fitted best. Thus, kaolinite clays have been proved as a potential adsorbent for the removal of chlorotriazine moleculesenAtrazineKaoliniteclayBatch processEquilibrium KineticsArticle
