Sorption of Atrazine (AT) on Nano-SiO₂ and Nano-Kaolinite

Abstract:

With the increasing use of nano-SiO₂ and nano-kaolinite, it is imperative to investigate their effect on the transport of aqueous contaminants. In this study, the extent and reversibility of sorption of AT on nano-SiO₂ and nano-kaolinite were examined using batch sorption experiments. Influence of ionic strength, pH and temperature was investigated. Sorption data were well fitted with Freundlich models. The sorption capacities were larger at low ionc strengths and low pHs. Nano-particle aggregate size is an important factor for the pH influencing process, which increase as the pH approach pHzpc. The sorption of AT on the two nano-particles is spontaneous.
