Waste-Tire-Derived Activated Carbon as Efficient Adsorbent of P-Nitrophenol from Wastewater

Figure 6

The adsorption capacity and removal rate of 650-2 for PNP under different initial concentrations; the initial concentration of PNP is 10–500 mg L⁻¹ (25°C, pH = 5, C₀ at 10–500 mg L⁻¹, and adsorption time of 24 h).
