Kinetic and Isotherm Studies of the Removal of Zn2+ Ions from Aqueous Solution by Modified Poly(ethylene terephthalate) Fibers

Abstract

Poly(ethylene terephthalate) (PET) fibers (stretch ratio 2, 30 filament, 110 dTex) were received from Amir Kabir University and Technology (Tehran). Methyl methacrylate (MMA) and acrylic acid (AA) were purchased by BDH Co. of England and after purification were used in all experiments. Bz2O2 after

Adsorption of Zinc(II) from Aqueous Solution Using Poly(ethylene terephthalate)-Grafted-Methyl methacrylate/Acrylic Acid

“…Polymerpropped reactive groups have been considered for the selective extraction processes of metal ions. Grafted poly(ethylene terephthalate) fibers can be improved undesirable properties of poly(ethylene terephthalate) such as low moisture regain, difficulty in dyeing, poor antistatic properties and because of high stability in acidic and basic media, fibers reactive agents have shown many advantages for removal of metal ions and dyes from wastewater [8][9][10][11][12][13][14][15][16] . Zinc toxicity from excessive englut is lower than other heavy metals.…”
