(a) Cr6+ ions desorption% from CAC-IO (2.0 g L–1) and the regenerated CAC-IO was used to promote Cr6+ ions (100 mg L–1) adsorption cycles using pH = 1.0, (b) MV40 dye was desorption% from CAC-IO (1.0 g L–1) and the regenerated CAC-IO was used to promote MV40 dye (400 g L–1) adsorption cycles using pH = 2.07.
