Bisulfit oxidation
The bisulfite ion (IUPAC-recommended nomenclature: hydrogensulfite) is the ion HSO 3. Salts containing the HSO 3 ion are also known as "sulfite lyes". Sodium bisulfite is used interchangeably with sodium metabisulfite (Na2S2O5). Sodium metabisulfite dissolves in water to give a solution of Na HSO 3. Na2S2O5 + … See more The bisulfite anion exists in solution as a mixture of two tautomers. One tautomer has the proton attached to one of the three oxygen centers. In the second tautomer the proton resides on sulfur. The S-protonated … See more Tautomerization There exist two tautomers of bisulfite. They interconvert readily but can be characterized individually by various spectroscopic … See more WebNov 15, 2024 · Drinking water treatment using UV/H 2 O 2 advanced oxidation typically results in residual H 2 O 2 that requires quenching to minimize its interference with downstream processes. Chemical quenching using chlorine or bisulfite are options, but there is some uncertainty in the literature about the kinetics of the bisulfite reaction, with …
