Investigation of Adsorption Behavior of Cu2O Submicro-Octahedra towards Congo Red
Figure 4
Adsorption curves of the aqueous solution of congo red (10 mg L−1, 200 mL) in the presence of Cu2O octahedra (0.05 g–0.15 g) at different intervals, where denotes the concentrations of CR changing following adsorption time and denotes the initial concentration of CR.
