ABSTRACT

Industrialization has increased significant pollution of water resources and has caused many harmful effects. In India, the ground water contamination with respect to nitrate has been observed in states like Andhra Pradesh, Bihar, Haryana, Himachal Pradesh, Karnataka, Rajasthan, Tamil nadu, Punjab, Kerala, Orissa, and Gujarat. In this work, adsorption experiments were carried out using electrochemical method for the removal of nitrate from groundwater. Synthetically prepared water with initial nitrate concentrations ranging between 60 to 80 mg/L were used for the experiments. The electrochemical (EC) experiments were conducted in a glass beaker of working volume of 1.0 L. A DC power supply, ammeter, voltmeter and magnetic stirrer were provided for the completion of EC cell set up. The studies were carried out for electrode like aluminum. Synthetic water containing 70-80 mg/L nitrate nitrogen was treated in the reactor for an electrolysis duration of 30, 60 and 120 minutes respectively.
