Development of FACTS Procedures for Combined Chlorine and Ozone in Aqueous Solutions.
Abstract
Most colorimetric procedures for chlorine analysis in treated water and wastewater suffer from the fact that they are not specific for free available chlorine. However, the FACTS (Free Available Chlorine Test with Syringaldazine) procedure is specific for free available chlorine in the presence of the common interferences found in water. This study describes the research leading to the modification of FACTS to give a procedure for total available chlorine and combined available chlorine. The modified FACTS procedure obeys Beer's Law through the range of 0-10 mg/1 total available chlorine (as Cl2) with a lower limit of 0.2 mg/1 (as Cl2). Ozonation is being explored as an alternative method for disinfection. Therefore, the FATCS procedure has also been modified to determine residual ozone in aqueous solutions obeying Beer's Law through the range of 0-6 mg/1 ozone with a lower limit of 0.2 mg/1 ozone.
