Comparison of membrane immobilized zero-valent iron nanoparticles for RED ME4BL azodye degradation

Textile industries are hailed as one of the major environmental polluters in world, owing to their release undesirable dye effluents. Synthetic dyes do not adhere fabric firmly and released into aquatic ecosystem effluent. Consequently, consistent wastewater from numerous textile without previous treatment has detrimental effects on human health. Treatment methods currently being used fail degrade effluents have own shortcomings. Immobilized nanoparticles been extensively studied for remediation because many advantages over conventional methods. The present study aimed compare efficiency two different carrier matrices [namely Poly(vinylidene fluoride) Polyurethane] iron nanoparticle decolorization activity an azo (RED ME4BL). Scanning Electron Microscopy was carried out show deposition membrane. reaction kinetics bare were compared with that immobilized nanoparticles, all found follow pseudo-second-order kinetics. Polyurethane showed a significant degradation RED ME4bl than nanoparticles. This paper also demonstrates relatively newer method immobilisation using synthetic polyurethane form.
