(A) The impact of time on adsorption ability of RR2 dye by NiONPs and Cr/NiONPs (NPs mass: 0.1 g in 100 mL of RR2 solutions, the initial RR2 conc.: 60 mg/L, t = 25 °C, at 150 rpm, pH 6). (B) Adsorption isotherm of RR2 dye on both NiONPs and Cr/NiONPs (C) and (D) the impact of RR2 concentration and the mass of NiONPs and Cr/NiONPs on the adsorption capacity and R%.
