Figure 7
The effect of pH on the removal rate and adsorption capacity of Cd2+ (a) and Pb2+ (b). Adsorption conditions: IP4 dosage: 0.05 g; adsorption time: 60 min; adsorption temperature: 25°C; agitation speed: 180 rpm; initial concentration of Cd2+: 100 mg/L; initial concentration of Pb2+: 150 mg/L; and solution pH: 2-8.
