Coefficient of ozone mass transfer during its interaction with an aqueous solution of formic acid in a bubble column reactor

Аннотация

A way of determining the coefficient of ozone mass transfer between the gas phase and liquid aqueous phase using a test compound (formic acid) is described. The values of ozone mass transfer coefficient (in aqueous solutions of 0.1–0.55 М HClO₄ and 0–1 М НСООН, and in 0.75 М H₂SO₄, 0.125 М KHSO₄, and 0–2 М НСООН) are determined along with the rate constants of the reaction of О₃ with undissociated НСООН molecules and formate ions at 21 ± 1°С.
