3.10 Fenton Reaction

What is the primary reactant responsible for generating hydroxyl radicals in the Fenton Reaction?

• Hydrogen peroxide

• Ferrous sulfate

• Hydrochloric acid

• Sodium chloride

The Fenton Reaction is a chemical process used to generate hydroxyl radicals through the reaction between:

• Hydrogen peroxide and ozone

• Ferrous sulfate and hydrogen peroxide

• Sodium chloride and sulfuric acid

• Carbon dioxide and water

Hydroxyl radicals (•OH) are highly reactive due to:

• Their positive charge

• Their unpaired electron

• Their stable molecular structure

• Their resistance to oxidation

The generation of hydroxyl radicals in the Fenton Reaction is dependent on the presence of:

• Ultraviolet light

• Oxygen

• High temperature

• Acids

In wastewater treatment, the Fenton Reaction is primarily used to:

• Enhance the color of effluent water

• Remove organic pollutants

• Increase the pH of wastewater

• Promote bacterial growth

Which of the following pollutants can be effectively treated using the Fenton Reaction?

• Heavy metals

• Inorganic salts

• Organic dyes and compounds

• Sediments

Fenton-like reactions are commonly applied in wastewater treatment for the removal of which specific pollutant group?

• Phosphates

• Bacteria

• Volatile organic compounds

• Heavy metals

What role does the Fenton Reaction play in the removal of persistent organic pollutants from wastewater?

• It converts them into harmless gases

• It degrades them into less harmful compounds

• It concentrates them for easy removal

• It has no effect on organic pollutants

Fenton-based processes are often combined with other treatment methods in wastewater treatment to:

• Increase the pH of the water

• Reduce operational costs

• Enhance the color of effluent water

• Improve overall treatment efficiency

The Fenton Reaction kinetics are typically described as:

• Zero-order reactions

• First-order reactions

• Second-order reactions

• Reversible reactions
