Description
Nitrate (NO3-) is a well-known pollutant of groundwaters mainly because of its wide use in fertilizers, animal and industrial waste. It can also be found in lakes, rivers, and seas. High concentration of nitrate in drinking water can lead to many health issues. Its reduction in water sources is necessary to decrease the spread of disease. This study focuses on researching the materials that can catalyze nitrate reduction reaction by conversion of nitrate to nitrogen gas/ammonia through electrochemical reduction. Electrochemical method has attracted growing interest since it offers operational versatility and environmental sustainability. Due to these advantages, our study is going to focus on evaluating carbon black-supported iron (Fe) containing catalysts for the NO 3 - reduction. Through performing Linear Sweep Voltammetry (LSV) in electrolyte 0.1M KOH (without KNO 3) and 0.1M KOH with 0.1M KNO 3, differences between current density in LSV are observed on the catalysts prepared. This work established the method of screening efficient catalysts for electrochemical reduction of nitrate.
