Neutralization takes place as the soluble hydroxyl ions from magnesium hydroxide are consumed by the acid (Martin, Davis, and Chewning, 1991). Additional hydroxyl ions are released as the magnesium hydroxide particle dissolves when more acidity is generated. As a result, magnesium hydroxide provides long lasting alkalinity and better pH control.

plants using wet flue gas desulfurization (FGD) systems, the reduction in flue gas temperature can result in in-creased H 2 SO 4 condensation and subsequent corrosion. In such cases, the flue gas may require reheating to ensure it remains above the dew point, thereby resulting in in-creased operation costs.13 REGULATORY OVERVIEW
byproduct, recycling magnesium hydroxide byproduct, hydriding the magnesium, and estimating the costs of the processes. An experimental task is directed at evaluating a promising technology under development at Boston University to electrolytically convert MgO to Mg.
The invention is a unique composition of magnesium hydroxide nanoparticles—Mg(OH) 2 NPs—and methods for using the composition to kill plant pathogens effectively. An alternative to Cu-based bactericides and fungicides, the composition is low in both phytotoxicity and cytotoxicity and does not hamper germination and seedling growth.
· Magnesium hydroxide vs caustic soda / sodium hydroxide demonstration A safe and cost effective alternative to the use of sodium hydroxide (caustic soda) for wastewater alkalinity and pH adjustment. Magnesium hydroxide is the least expensive and most powerful alkaline chemical treatment available on the market for pH control applications.
