Abstract
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 (MTSO), which can be separated easily by high-performance liquid chromatography on a reversed-phase column and detected by ultraviolet spectroscopy at a wavelength of 230 nm. MTSO is a commercially available solid substance which can be used as an external standard for calibration. Therefore, calibration with the unstable PAA can be avoided
