Degradation of the Reactive Blue 4 Dye in Aqueous Solution Using Zero-Valent Copper Nanoparticles

Figure 3

Effect of different reaction conditions on the degradation of RB4 dye by zero-valent copper nanoparticles: “■”: presence of TBA (1,0 mmol L⁻¹); “●”: no scavenger (without the presence of TBA); “▲”: under oxic conditions (with bubbling of synthetic air); “▼”: under anoxic conditions (nitrogen atmosphere). Experimental conditions: = 15,0 mg L⁻¹; nZVC dosage = 1,00 g L⁻¹; = 25°C.
