What is Peracetic Acid?
Peracetic acid (PAA) is a versatile oxidizing disinfectant that is formed from a reaction between acetic acid and hydrogen peroxide. It is commonly used as a sanitizing agent in the food and beverage industries to disinfect equipment, pasteurizers, tanks, pipelines, evaporators, fillers, and contact surfaces in food processing plants. The pulp and paper industry uses peracetic acid as a delignification and bleaching agent. PAA is also becoming a popular biocide in wastewater treatment and is even used in aquaculture tanks. Part of the rising popularity of peracetic acid use is because PAA decomposes into non-toxic by-products.
About Our Test Kits.
CHEMetrics’ colorimetric test kits for the analysis of PAA in water are available in both visual and instrumental formats. Our self-filling ampoule technology reduces analyst exposure to reagent chemicals and test procedure complexity. All of our PAA test kits employ the total chlorine DPD method which produces a pink color in the presence of PAA. Recently Standard Methods for the Examination of Water and Wastewater published a validated PAA test procedure based on this method.
If you are testing high concentrations of PAA, dilution may be used to extend the range of our test kit. You can find more information on our Sample Dilution Instructions.
