Reactions of dissolved organic matter with hydroxyl radicals: effects on DOM molecular properties and modulation by Cu( ii )

Key Points

• This research examines how hydroxyl radicals interact with dissolved organic matter and the role of copper in modulating these interactions.
• Analyzed reactions of hydroxyl radicals with different types of dissolved organic matter.
• Investigated changes in molecular properties of dissolved organic matter post-reaction.
• Explored the modulation effects of Copper II on these interactions.
• Hydroxyl radicals significantly alter the molecular properties of dissolved organic matter.
• The presence of copper II affects the reactivity and resulting molecular changes in dissolved organic matter.
