Fenton like oxidative degradation of toxic water pollutants by iron nanoparticles synthesized via facile green route using waste iron rust as the iron precursor

Corrosion of iron by oxidation is a global problem that affects the economy and gives rise to environmental pollution. Iron rust oxide or hydroxide iron, it can be used as secondary source which will lead its management well reduce pressure on primary sources. In present study, waste was precursor for synthesis nanoparticles via green route using extract dried Jatropha leaf. Synthesized were characterized different instrumental techniques. bear an extremely large specific surface area 190.2 m2/g. The catalytic potential synthesized tested degradation toxic organic pollutants phenol p-nitrophenol (PNP) in aqueous solution. Both removed rapidly initial 30 minutes reaction time. Optimization removal process done varying variables. Maximum (~98%) PNP (~95%) achieved at 0.1 g/L concentration nanoparticles. rate determined pseudo-first-order pseudo-second-order kinetics data found followed best kinetics.
