Unlocking the Potential: Charcoal-Based Materials for Nitrate Removal in Water

This study delves into the synthesis of M-oxides (aluminum, iron, magnesium, zinc) supported on charcoal through wet impregnation, exploring their potential in nitrate removal from water. The research investigates both the structural and compositional aspects of the solid material incorporation and the modifications experienced by the carbonaceous support.

This study explores the synthesis of M-oxides (aluminum, iron, magnesium, zinc) supported on charcoal for nitrate removal from water. Using wet impregnation, the research examines the structural and compositional aspects of the incorporated solid material and the modifications in the carbonaceous support. The material’s performance is compared to charcoal as a control group.

Characterization reveals that wet impregnation results in a composite material with a porous carbon matrix, its structure influenced by the precursor. However, there is a notable loss of carbonaceous support during synthesis, varying with different precursors. Zinc oxide stands out as the most effective in removing nitrate from water compared to the control group.

The study concludes that wet impregnation enables the creation of materials enhancing nitrate removal. Despite improvements, the significant change in the carbonaceous support raises questions about its influence on nitrate removal, warranting further investigation.
