Synthesized Nickel Nanoparticles (Ni-NPs) Confirmed as Catalyst for Degradation of Carcinogenic Novacron Ruby S-3B (NR) Dye in Aqueous Medium

The main aim of this research was to investigate the catalytic effect of the Nickel Nanoparticles (Ni-NPs) for the degradation of Novacron Ruby S-3B (NR) dye in water-based solutions. An average size of 53 nm of Nickel Nanoparticle was synthesized by chemical reduction method reaction with NiCl ₂ where hydrazine was used as reducing agent in basic medium. Through the synthesis process various reaction conditions was varied as contact time, temperature and reactant concentration for better Ni-NPs yield. The particle size of Ni-NPs was determined by morphology studies using SEM and XRD. Further the synthesized Ni-NPs was used as catalyst for the degradation of NR dye in aqueous. The catalytic degradation of NR dye was determined by measuring the dye concentration reduction, amount of synthesized Ni-NPs catalyst used, with the reaction condition variations, as the effect of pH , temperature, and time variations. A maximum of Novacron Ruby S-3B (NR) dye degradation was estimated 94.262% after 180 min treatment at dye concentration 20 mgL ^-1 at 55ºC and pH -6 using synthesized Ni-NPs catalyst 20ppm.
