Development of FACTS Procedures for Combined Chlorine and Ozone in Aqueous Solutions by Nina Matheny Roscher( Book )

2 editions published in 1978 in English and held by 2 WorldCat member libraries worldwide

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.

Comparison of Facts and DPD-Steadifac Procedures for Free and Combined Chlorine in Aqueous Solution( Book )

1 edition published in 1980 in English and held by 1 WorldCat member library worldwide

In a continuing effort to develop a superior colorimetric test procedure for determining free available chlorine in aqueous solution, a study was designed to compare the FACTS (Free Available Chlorine Test with Syringaldazine) with the recently modified DPD procedure, DPD-STEADIFAC. It was shown that the DPD-STEADIFAC and a minor modification are more specific for free chlorine in the presence of mono- and dichloramine than the DPD procedure. The DPD and DPD-STEADIFAC Modified procedure were shown to have comparable accuracy and precision. All of the test procedures showed intrusion of NC13 into the free chlorine reading. The lower limit of detection for the FACTS and DPD procedures were 0.014 and 0.021 mg/L as Cl2, respectively. (Author)
