“…These requirements could be fulfill when Nylon-6 fibers contain quaternary ammonium groups (QAG) capable of forming a complex with the initiator (peroxides) [12]. Further decomposition of the obtained complex leads to the formation of free radicals on the Nylon-6 fibers thus facilitating their direct grafting with different vinyl monomers with high rate and without homopolymer formation [13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

I N 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 Cu 2+-K 2 S 2 O 8 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 Cr 2 O 7-2 , SO 4-2 was investigated. The influence of various adsorption parameters on the degree of extraction (R %) and adsorption capacity (SC mg/g) was calculated.

“…It is well known that quaternary ammonium groups (QAG) can form complexes with peroxides. This was successfully used for grafting PA-6 fibers with different vinyl monomers [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32].…”

EMOVING the hazardous metals from wastewater especially industrial drainage is very important for preventing health problems in human beings, plants and animals. The ion exchanger has constructed as primary line of safeguards for that goal. In this study grafted polyamide-6 (PA-6) fibers with polymethacrylic acid (PMAA) was used as materials for the ion exchangers. Grafting was achieved under required time and temperature and the factors affecting the graft process were studied. The efficiency of the grafted fibers for adsorption of Cu 2+ , Pb 2+ and Cr 6+ was evaluated. The effect of adsorption parameters such as pH, duration of adsorption, initial ion concentration and the adsorption temperature on the degree of extraction (R %) and adsorption capacity (SC, mg/g) was studied. Optimization the conditions for the preparation on laboratory scale, adjustment and adaptation of these conditions to suit the production of these grafted fibers on pilot scale was accomplished.
