- Abstract
The paper presents studies conducted for the determination of chlorine dioxide, free chlorine and total chlorine in drinking water collected from the public water network in Baia Mare, Maramureș county, Romania. The method used is photometric, the device used in the experiment is a photocolorimeter for boilers and cooling towers purchased from Hanna Instruments. Chlorine dioxide content was determined using the Chlorine Dioxide method and four types of reagents: Chlorine Dioxide Reagent A, B, C, D; the result of the determination being 0.05 mg/L. Free chlorine was determined with the Chlorine (Free) method, the instrument displayed the result 0.13 mg/L Cl2; chlorine being a poison for microorganisms, it is used, in small concentrations, as a disinfectant for drinking water. The total chlorine in the analyzed water sample had a value of 0.20 mg/L Cl2, it was determined with the Chlorine (Total) method, the reagent used in the experiment for this method was a powder Code HI93711-0.
