Removal of Heavy Metals from Industrial Effluents using Burnt Potato Peels as Adsorbent

The presence of heavy metals in water makes water unfit for use and causes various hazardous health problems. This research investigates the physical and chemical properties of the collected industrial effluent samples of different industries and the use of burnt potato peels (BPP) as adsorbents to remove heavy metal ions from industrial effluents. Various parameters such as pH, adsorbent volume, and contact time were investigated. The concentration of heavy metal ions was accurately quantified using complexometric titration and atomic absorption spectroscopic analyses. Various heavy metals such as Co+, Mg+, Fe+, Pb+, and Cd+ were found in the samples with varying concentrations. The burnt potato peels showed the maximum adsorption of about 61% at pH 9, 60 min contact time, 0.5 g of burnt potato peels, and 10 mg/L of sample concentration.
