CHEMets Ozone Visual Method

CHEMets Ozone Visual Method

Ozone is a strong oxidising agent and is used as an alternative to chlorine as a biocide in the disinfection of drinking water. Ozone is used to remove odour, de-colourise, and to control algae and other aquatic growths. Ozone is also used in various disinfectant / sterilisation processes in the food and beverage and pharmaceutical industries.

The DPD Method
In the USEPA-approved DPD methodology, free chlorine reacts with DPD to form a pink product. When ammonia or amines are present, some of the chlorine may exist as combined chlorine. Combined chlorine will not interfere with the free chlorine results, provided the readings are taken at one minute. To determine total chlorine (the sum of free and combined), use the A-2500 Activator Solution (potassium iodide) supplied in the kit. Results are expressed as ppm (mg/L) Cl2.

Material Safety Data Sheets are provided in test kits.

CHEMets ampoules are designed for maximum simplicity and accuracy. Each glass ampoule is 7 mm in diameter, 100 mm in length, with a tapered, pre-scored tip; reagents are vacuum-sealed inside.

Various free halogens and halogenating agents produce colour with the reagent. Chromate in samples below 25 ppm will not interfere with results. Results are expressed as ppm (mg/L) O3.
