Effective Adsorption and Optimization of Chromium (VI) Using Potato Peels as Bio-Sorbent

Abstract

Introduction: The potato (Solanum tuberosum) is the most important food crop in the world. It is the 4th most important part of daily consumption in the human diet after rice, wheat, and corn. The treated water can be used as potable water for agricultural and industrial purposes. The water from the different areas of Jaipur is found to have deteriorated  water quality. Water pollution is a major environmental concern these days and is the main cause of major health issues.

 Objective: The present work is carried out to study the physicochemical characteristics of water samples collected from different areas of Jaipur using activated carbon prepared from potato peels.

 Methods: The wastewater of different areas is characterized by extreme fluctuations in many parameters, such as pH, EC, salinity, TDS, and chromium concentration.

Results: The use of low-cost adsorbents obtained from potato peels is highly productive because they are not only cost-effective but also economical. The adsorbent prepared from potato peels is found to be very effective as it comprises bioactive compounds and is also rich in phenolic groups.

Conclusion: This study is evaluating the efficacy of potato peels in removing Cr(VI) ions from aqueous solutions by adsorption. The efficacy was investigated by batch experiments to evaluate the influence of pH and initial ion concentration, agitation speed , contact time Keywords: Potato Peel , Cr VI, Activated Carbon, Batch experiment.
