The study presents experimental results determining the free chlorine content by UV-Vis absorption spectrophotometry using a calibration curve with the standard solution NaOCl. The chlorine in exists an aqueous solution as HOCl and OCl- depending on pH of media, that are knowm as free chlorine. The maximum absorption wavelengthts of OCl- and HOCl in aqueous media formed from sodium hypochlotrate are 291 and 292 respetively. Based on these wavelenghts OCl- and HOCl content might be determined using UV-Vis absorpton spectrophotometric method resulted in good data.
