The oxidation of organic sulphides is very fast with peracids and very slow with hydrogen peroxide. Thus, addition of an excess of methyl p-tolyl sulphide to a mixture of an organic peracid and hydrogen peroxide results in the formation of methyl p-tolyl sulphoxide equimolar with the peracid. The gas-chromatographic determination of the residual sulphide, or of the produced sulphoxide, affords a quantitative evaluation of the peracid present in the mixture. The method has been applied to the… 
Reagent for the high-performance liquid chromatography determination of peroxycarboxylic acids
The synthesis and application of a new thiomethoxy-functionalised azo compound for the determination of peroxycarboxylic acids is described. 2-[(3-{2-[4-Amino-2-(methylsulfanyl}phenyl]-1-
Photometric and Gas-Chromatographic Determination of Hydrogen Peroxide and Peroxybutanoic Acid in Oxidized Butanoic Acid
Procedures were developed for determining hydrogen peroxide and peroxy acids mixed with peroxide compounds of other classes in the oxidation products of butanoic acid with atmospheric oxygen and
Determination of Peroxyacetic Acid Using High-Performance Liquid Chromatography with External Calibration
A new method for the determination of peroxyacetic acid (PAA) in aqueous solutions is described. Methyl p-tolyl sulfide (MTS) is oxidized by PAA, forming the corresponding methyl p-tolyl sulfoxide
ELECTROANALYSIS OF PERACETIC ACID IN THE PRESENCE OF A LARGE EXCESS OF HYDROGEN PEROXIDE
The simultaneous electroanalysis of peracetic acid (PAA) and H2O2 in the presence of a large excess of H2O2, up to hundred times the concentrations of PAA, has been presented for the first time.
A High-Throughput Microtiter Plate Based Method for the Determination of Peracetic Acid and Hydrogen Peroxide
TLDR
The development of a high-throughput microtiter plate based assay based upon the well known and trusted titration chemical reactions for the sequential determination of hydrogen peroxide specifically and the total amount of peroxides present in solution is described.
