Optical properties containing of bioinspired Ag2O nanoparticles anchored on CA/PES polymer membrane shows an effective adsorbent material

Abstract

Effective and selective removal of organic dye from water systems is a pressing global challenge for both drinking water and wastewater purification. Removal of dyes from wastewater is a challenging task, the combined use of inorganic nanomaterials and membrane technology to overcome these problems using adsorption. In this paper, optical properties containing of bioinspired Gomutra mediated Ag2O NPs prepared by hydrothermal method and it’s anchored onto CA/PES polymer composite membrane via phase inversion method for enhance the surface of the membrane properties. According to the resulting experiment pristine membrane there is no adsorption ability towards dye molecules but with 0.5 wt.% of Ag2O NPs dosage of membrane showed superior removal efficiency of 88% and 77% at MB dye and textile effluents. The most effective temperature, pH and concentration were found to be 273 K, pH 9 and 1 ×10-5 M. Kinetic studies exhibit the rate of the reaction for MB dye shows R2 = 0.8780 and R2 = 0.9607 for textile effluents which obeys the pseudo first order reaction. Furthermore, when non-treated effluent samples were compared to those treated with prepared membrane all physiochemical parameters such as temperature, pH, BOD, COD, TDS, sulfate, chloride and hardness showed significant decrease in concentration. Therefore, the modified composite material demonstrates that highly efficient and universally applicable for wastewater treatment.
