Method
References: Developed by CHEMetrics, Inc.
Because it is a strong disinfectant, peracetic acid is an excellent sanitizing agent for the food and beverage industry. Peracetic acid is used to disinfect equipment, pasteurizers, tanks, pipelines, evaporators, fillers, and contact surfaces in food processing plants. It is especially effective in eliminating the osmotolerant microbes (e.g. the yeast Zygosaccharomyces bailii) in beverage plants producing high-sugar products. The pulp and paper industry uses peracetic acid as a delignification and bleaching agent.
In the Peracetic Acid DDPD test method, the sample is treated with an excess of potassium iodide. Peracetic acid oxidizes the iodide to iodine. The iodine then oxidizes DDPD, a methyl-substituted form of DPD (N, N-diethyl-p-phenylenediamine) to form a purplecolored species that is directly proportional to the peracetic acid concentration in the sample. Results are expressed as ppm (mg/L) peracetic acid.
Various oxidizing agents such as halogens, ozone, ferric ions, and cupric ions will produce high test results. Hydrogen peroxide does not interfere. |
