Removal of boron using glucamine containing nano and micro fibrous ion-exchange materials

Abstract

Fibrous lon-exchangers me rather promising with regard to their good sorption capacity mainly because of their large surface area to volume ratio. This study is aimed at establishing a comparison between nano- and micro- fibrous materials for boron removal. The materials chosen for this study were prepared via radiation induced grafting to attach an epoxy containing monomer group and subsequently functionalized with N-methylghicamine. The performances of the nano- and micro ion-exchangers were compared on a batch basis to determine the boron removal percentage The parameters investigated were adsorbent dosage, time. pH and initial boric acid concentration. Based on the results obtained nano-fibrous ion-exchangers were found to perform better than micro-fibrous 1011- exchangers.
