The CHEMetrics test kits for the determination of Peracetic Acid in aqueous solutions are based on patented Self-Filling Reagent Ampoule technology, and employ the DPD method, delivering sensitivity and accuracy within two minutes or less. Premixed. Premeasured. Precise. Each kit contains 30 tests. Suitable for food and beverage and pulp and paper manufacturing as well as waste water applications.
The DPD Method
In the Peracetic Acid DPD test method, the sample is treated with an excess of potassium iodide. Peracetic acid oxidises the iodide to iodine. The iodine then oxidises DPD (N, N-diethyl-p-phenylenediamine) to form a pink-colored species that is directly propoptional to the peracetic acid concentration in the sample. Results are expressed as ppm (mg/l) peracetic acid.
Various oxidising agents such as halogens, ozone, and cupric ions will produce high test results. Hydrogen peroxide does not interfere if present at levels comparable to the peracetic acid levels.

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 including pasteurisers, tanks, pipelines, evaporators, fillers and chillers and other contact surfaces in food processing plants. The pulp and paper industry uses peracetic acid as a delignification and bleaching agent. Peracetic Acid is also coming into use as a biocide in waste water applications.
