Development of pilot scale system for production of nylon-6 fibers grafted with polydimethylaminoethylmathacrylate (PDMAEMA) for the application as ion exchange

Abstract

IN this work an affective and simple technology for pilot scale production of grafted Nylon-6 fibers with Polydimethylaminoethylmathacrylate (PDMAEMA) for ion exchange application is suggested. This technology consists of the creation of antimicrobial substance (AS) in Nylon-6 fibers followed by grafting with dimethylaminoethylmathacrylate (DMAEMA) using Cu2+-K2S2O8 redox system. Factors affecting the yield of grafted PDMAEMA were investigated and the optimal conditions for grafting process were evaluated. The availability of modified Nylon-6 fibers grafted with PDMAEMA as polymer sorbent for removal of cations as Cu+2, Pb+2 and anions Cr2O7-2, SO4-2 was investigated. The influence of various adsorption parameters on the degree of extraction (R %) and adsorption capacity (SC mg/g) was calculated.
