| Abstract |
A description is given of work undertaken to develop a simple, specific, and reliable method for ozone. Reactions of ozone with several 1-alkenes were studied at room temperature (25C). Eugenol (4-allyl-2-methoxy phenol), when reacted with ozone, was found to produce relatively large amounts of formaldehyde as compared to other 1-alkenes tested. The method described was compared with alkaline iodide method for the determination of various concentrations of ozone in the range of 0.05 to 2.0 ppm. The reactions of ozone with eugenol were found to yield stoichiometric amounts of formaldehyde. Hydrogen peroxide, peracetic acid, sulfur dioxide and various reducing agents commonly present in the air, do not interfere with the method. Formaldehyde when present in the air, must be determined simultaneously. Any formaldehyde monitoring equipment can be easily adopted for the determination of ozone. (Author) |
