“…The concentration of PAA solution was determined by the HPLC based on the procedures described by Pinkernell et al 17 : 1 mL of sample or standard solution was mixed with 2 mL of a solution of 10 mM methylp-tolylsulfide ͑MTS͒ in methanol in a volumetric flask. Watermethanol mixtures were added to a total volume of 10 mL.…”

An electrochemical method for the preparation of peroxyacetic acid ͑PAA͒ using in situ generated hydrogen peroxide on the gas diffusion electrode ͑GDE͒ as an oxygen cathode has been described. Effects of several experimental conditions, such as current density, oxygen feed rate, electrolyte concentration, electrolytic cell configuration, flow rate of electrolyte solution, and Pt catalyst incorporated into GDE upon the cathodic reaction of oxygen to hydrogen peroxide as well as the production of PAA solution, have been investigated. Hydrogen peroxide is electrogenerated by the reduction of oxygen on the GDE and the generated hydrogen peroxide can undergo a chemical reaction with acetic acid in the presence of solid superacid, Nafion-H as a catalyst to produce PAA. It is also suggested that the formation of PAA is initiated by the active oxygen, O*, electrogenerated on the cathode surface. The current efficiency for the production of PAA was found to be 28% at a current density of 1 A/dm 2 and electrolyte flow rate of 160 mL/h. A probable reaction mechanism for the formation of PAA is proposed.

“…It has been found that high exposure and eye contact will cause severe health problems. For the above reasons, many studies were focusing on developing reliable and commercial methods to detect its aqueous concentration (Davies and Deary, 1988;Pinkernell et al, 1996;Ruttinger and Radschuweit, 2000;Awad, et al, 2003), and to monitor its airborne concentration on a regular basis in workplace environments (Effkemann et al, 1999;Hecht et al, 2004;Henneken et al, 2006). However, field measurements of PAA are extremely sparse (Fels and Junkermann, 1993;Walker et al, 2006), and hence, the limited data restrain better understanding the role of PAA on atmospheric chemistry.…”

Abstract. Peroxyacetic acid (PAA) is one of the most important atmospheric organic peroxides, which have received increasing attention for their potential contribution to the oxidation capacity of the troposphere and the formation of secondary aerosols. We report here, for the first time, a series of data for atmospheric PAA concentrations at urban and rural sites, from five field campaigns carried out in China in summer 2006, 2007 and 2008. For these five measurements, daytime mean (08:00-20:00 LT) PAA concentrations on sunlit days were 21.4-148.0 pptv with a maximum level of ∼1 ppbv. The various meteorological and chemical parameters influencing PAA concentrations were examined using Principal Factor Analysis. This statistical analysis shows that the local photochemical production was the major source of PAA, and its concentration increased with increasing temperature, solar radiation and ozone but decreased with increasing NO x (NO and NO 2 ), CO, SO 2 , and relative humidity. Based on the dataset, several issues are highlighted in this study: (i) Because PAA is a product from the photochemical oxidation of some specific volatile organic compounds (VOCs) that lead to acetyl peroxy radicals, the importance of various VOCs with respect to the PAA formation is therefore ranked using the incremental reactivity method. (ii) The contribution of PAN thermal degradation to PAA formation under conditions of different NO x concentrations is estimated based on the chemical kinetics analysis. The result shows that PAN seems to play an important role in the formation of PAA when the NO/NO 2 concentration ratio was less than 0.2 and PAA would correspondingly have feedback on the PAN-NO x cycle. (iii) PAA and other peroxides, such as methyl Correspondence to: Z. M. Chen (zmchen@pku.edu.cn) hydroperoxide (MHP) and H 2 O 2 , usually exhibited a similar asymmetric shape typically shifted to the afternoon. However, under some conditions, H 2 O 2 diurnal cycle was out of phase with MHP and PAA. The combination of linear regression and kinetics analysis indicate that the formation and removal processes of H 2 O 2 may be different from those of MHP and PAA. (iv) Considering that PAA is the reservior of free radicals, its fate is expected to have an effect on the free radical budget in the atmosphere. A box model based on the CBM-IV mechanism has been performed to access its influence on the radical budget. We suggest that the detailed information on PAA in the atmosphere is of importance to better understand the free radical chemistry.
