Fig. 7. Effect of initial pH (pHi) on the removal efficiency of Cr(vi) by the RBC-TiO2@C nanocomposite, pHf and ΔpH. Here, pHf and ΔpH represent the final pH and change in pH after the adsorption experiment, respectively (dosage@0.8 g L−1; 100 mg kg−1 initial concentration; 288 K temperature; 150 rpm shaking speed).
