β-Phosphonated Glycine Pendant Groups Grafted on Styrene-6.7% Divinylbenzene Copolymers: Synthesis and Their Application as Photocatalysts

Environmental pollution from organic contaminants caused by textile dyeing is a real danger. Wastewater the industry has high loads, as well dyes and chemical compounds used in their preparation. Among azo dyes, Congo red (CR) dye widely model experimental studies of wastewater treatment. Heterogeneous photocatalysis consists UV or VIS light irradiation various types water presence solid catalyst; it considered an important technique for purification reuse aqueous effluents. In present study, two novel β-phosphonate-type glycine pendant groups grafted on S-DVB copolymer were decontamination polluted water. They characterized FTIR spectroscopy, scanning electron microscopy, EDX thermogravimetric analysis UV-VIS spectroscopy. By using 25 mg/L initial concentration catalyst 1 g/L 240 min irradiation, efficiency 98.6% case [(diethyl)(phosphono)methylene]glycine styrene-6.7% divinylbenzene (EthylAmAcid material), 83.1% [(dibenzyl)(phosphono)methylene]glycine (BenzylAmAcid respectively, was achieved.
