Neutralization (chemistry) - Wikipedia

In chemistry, ,neutralization, or neutralisation (see spelling differences) is a chemical reaction in which ,acid, and a base react quantitatively with each other. In a reaction in water, ,neutralization, results in there being no excess of ,hydrogen, or hydroxide ions present in the solution. The pH of the neutralized solution depends on the ,acid, strength of the reactants.

Acid, mine drainage (AMD) is a complex environmental problem, which has adverse effects on surface and ground waters due to low pH, high toxic metals, and dissolved salts. New bioremediation approach based on microbial fuel cells (MFC) can be a novel and sustainable alternative for AMD treatment. We studied the potential of MFC for acidic synthetic water treatment through pH ,neutralization, in ...

Specific to strongly acidic ,wastewater,, the traditional lime ,neutralization, produces massive hazardous waste and present serious environmental risks. Thus, the recycling of purified ,wastewater, after the contained contaminants being removed has been proposed. However, among these contaminants, chloride ion (Cl(-I)) is rather difficult to remove.
