Role of Temperature and pH on the Dye Degradation Using Magnetic Nanoparticles Augmented Polymeric Microcapsule

Abstract:

Textile industry is one of the most significant worldwide water pollution sources. With the increased demand for textile products, the textile industry and its wastewater have been increasing proportionally. Microcapsule has remarkable advantages in engineering application for pollutants removal as encapsulation agent of nanoparticles (NPs) to drastically reduce the risk associated to nanotoxicity when it is in direct contact with surroundings. This work primarily focuses on the synthesis of magnetic nanoparticles augmented microcapsule in which role of temperature and initial pH was studied in relation to Fenton reaction of Methylene Blue dye. It is observed that high removal efficiency of the dye could be achieved with high temperature whereas highly acidic and alkaline condition could enhance degradation rate. The inherent catalytic and magnetic properties exhibited by Fe⁰/iron oxides NPs-PVDF microcapsules, compared to conventional activated carbon based absorbent, make them an attractive candidate to remove cationic dye from aqueous environment.
