Implication

Investigations reveal photochemical ozone significantly increases molecular chlorine yield in acidic solutions, suggesting enhanced oxidation pathways.

Key Points

The study aims to understand how molecular chlorine is released from chloride ions during ozonation in acidic solutions under UV light.
Analyzed the kinetics of molecular chlorine release during photochemical ozonation.
Used acidic aqueous solutions with varying pH levels (≤2 and ≤0.1).
Examined reactions under UV radiation (254 nm) alongside ozone.
Cl2 yield reached 70% in weakly acidic solutions at pH 2.
At very low pH (≤0.1), Cl2 yields from photochemical and dark ozonation were similar.
Hydroxyl radicals and hydrogen peroxide were identified as key species influencing oxidation of chloride ions.
