ABSTRACT
Nitrate contamination of drinking water is a dangerous. problem. The removal of nitrate presents a challenge because of the ion's high stability and soluble nature. Current technologies for removal of nitrate are lengthy and have several disadvantages. To avoid these disadvantages, chemical reducing agents are preferred to use. In recent years chemical methods of nitrate removal using zerovalent metals like iron [Fe[o]] and aluminum [Al[o]] have been studied intensively. Zero-valent magnesium [Mg[o]] is considered as a nontoxic and environmental benign metal, having high reduction potential as compared to Feoand Al[o]. It is tried here to develop a simplified quick and easy procedure to trace the extent of reduction of nitrate with Mg by just measuring the pH of the solution
