Various kinetic models’ study for orange-II and Sudan black dyes degradation by SSB-SN and CSS-SN nanoparticles. (a) and (b) represent the pseudo-first order kinetic study, whereas (c) and (d) are the pseudo-second order kinetic of orange-II and Sudan black dyes, respectively. (e) and (f) showing the Elovich kinetics model for orange-II and Sudan black dyes.
