Nitrate contamination of groundwater represents a threat to human health. Many researchers have studied zerovalent iron as a mean to remediate nitrate contamination. However, the application of such method is limited by ammonium production. This work investigates the use of microscale iron particles in association with zeolitite, a natural material containing zeolite, to remove nitrate and ammonium from groundwater. The association of the two materials is shown to lower the nitrate concentration in both deionized water and groundwater under the limit suggested by the European Union and to significantly reduce the ammonium concentration. The method is potentially applicable in water filtration.

Abstract
Nitrate contamination of groundwater represents a threat to human health. Many researchers have studied zerovalent iron as a mean to remediate nitrate contamination. However, the application of such method is limited by ammonium production. This work investigates the use of microscale iron particles in association with zeolitite, a natural material containing zeolite, to remove nitrate and ammonium from groundwater. The association of the two materials is shown to lower the nitrate concentration in both deionized water and groundwater under the limit suggested by the European Union and to significantly reduce the ammonium concentration. The method is potentially applicable in water filtration.Pubblicazioni consigliate
