Adsorptive removal of dyes and pollutants by Nickel nanoparticles synthesized using O. sanctum.
Adsorption efficacy relies on pH, contact time, adsorbent dose and adsorbate concentration.
Adsorption process obeys Langmuir isotherm and pseudo-second-order kinetics.
Physical adsorption is the predominant process on adsorption of dyes and pollutants.
