Efficient Removal of Cationic and Anionic Dyes from Synthetic and Real Wastewater by Plant-mediated Nickel Nanoparticles

In this study, Ni NPs were produced by biosynthesis method with the help of phytoconstituents present in Sahadevi plant (Vernonia cinerea) ethanoic extract namely nickel nanoparticles (SNPs). SNPs characterized using XRD, FT-IR, HR-FESEM. XRD study shows crystalline nature SNPs. employed as bioadsorbent for elimination dyes like cationic (BG) and anionic (CR) from aqueous media. Adsorption capacity was analyzed batch modes at various pH, initial dye concentration, contact time, isotherm, kinetics. The maximum adsorption (qm) shown Langmuir isotherm obtained 1666.7 mg g-1 case BG 666.7 CR dye, respectively. higher value coefficient recommended monolayer adsorption. kinetics information valuable suited to pseudo-second order R2 > 0.99 both dyes. proved be an efficient sorbent media can remove textile tannery discharges. Overall, suggests that use is safe secure, eco-friendly, cost-effective, which used removing colored organic effluents water bodies.
