Nickel (II) Removal from Synthetic Wastewater by Adsorption Using Waste Pea Shell

Abstract

In this study, the purification of Ni (II) ion in the adsorption process using ground waste pea pod material was investigated. Heavy metal removal from synthetic wastewater, variables such as dose, time, and pH optimization were tried to be determined. The research was carried out in the range of contact time (0-120 minutes), adsorbent amount (50-2000 mg/L), and pH (3-11) during treatment. It was determined that the optimum amount for waste pea pods used as adsorbents in dose optimization was 350 mg. The time optimization made in the mixer determined the optimum time as 60 minutes. Finally, pH optimization was done. Dose optimization, time optimization, and removal efficiency with original pH were found to be approximately 50%. As a result, it has been observed that waste pea pods can be used as a cheap adsorbent for the removal of Nickel (II).
