Catalytic Potential of Nano-Magnesium Oxide on Degradation of Humic Acids From Aquatic Solutions
Catalytic ozonation is a new and promising process used to remove the contaminants from drinking water and wastewater. This study aimed to evaluate the catalytic potential of nano-magnesium oxide (nano-MgO) for the removal of humic acids (HA) from water. Mg (NO3)2 solution was used to prepare MgO po...
