K-7904 features self-filling ampoules for the colorimetric analysis of the disinfectant peracetic acid (PAA) in water.

The Peracetic Acid CHEMets® test kit (0-1 & 0-5 ppm) comes in a plastic case and contains everything needed to perform 30 tests: Refill (R-7904), Low and High Range Comparators (C-7902 & C-7904), Activator Solution (A-2500), 25 mL sample cup (A-0013), and instructions.

Test Method:

ThePeracetic Acid CHEMets® Test Kit (0-1 & 0-5 ppm) employs the DPD chemistry. The sample is treated with an excess of potassium iodide. Peracetic acid oxidizes the iodide to iodine. The iodine then oxidizes DPD (N,N-diethyl-p-phenylenediamine) to form a pink colored species in direct proportion to the peracetic acid concentration. Various oxidizing agents such as halogens, ferric ions and cupric ions will produce high test results. Hydrogen peroxide does not interfere with this test if present at levels comparable to the peracetic acid levels.
