Using modified macadamia carbon by H2O2 as adsorbent to remove zinc (Zn2+) in wastewater

Abstract

Using modified macadamia carbon by H2O2 as adsorbent to remove Zn2+ with H2O2 25% in 48 hours. The Parameters, such as pH, dosage and adsorption time affect the processing ability of modified macadamia carbon H2O2. The maximum removal efficiency of 64.52% was obtained at a pH of 4.5, the processing time is 80 minutes, dosage 1.8 g/L and an initial heavy metal concentration of 25ppm.
