General description
The test can be used in
- Drinking water and mineral water
- Waters from aquaculture
- Wastewater
- Electroplating wastewater
- Disinfectant solutions
This test is not suited for seawater.
Method
In weakly acidic solution free chlorine reacts with diethyl-p-phenylenediamine (DPD) to form a red-violet dye. The chlorine concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color card.
The unique brilliance of the print and their fine color graduation allow precise analyses, even at the lower end of the concentration range. Due to the long test tubes a sensitive measurement range can be covered. Using the refill pack 1.14977 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
Application
- 3,3′,5,5′-tetramethylbenzidine as multi-colorimetric indicator of chlorine in water in line with health guideline values.: This study demonstrates the use of 3,3′,5,5′-tetramethylbenzidine as a colorimetric indicator for detecting chlorine levels in water, providing a cost-effective and simple method for ensuring water safety in compliance with health guidelines (Palladino et al., 2020).
- Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests.: Investigates the effectiveness of lateral flow assays for the quantification of free chlorine in water, highlighting their potential for quick and accurate chlorine testing in field settings (Schwenke et al., 2019).
- Improved residual chlorine test; the ortho-toluidine: arsenite method for testing water for true, false and chloramine residuals.: Describes a methodological advancement in measuring different forms of chlorine residuals in water, enhancing the accuracy of water quality assessments (GILCREAS FW, 1948).

Protocols
AQA Standard for free chlorine - Preparation of a standard solution for free chlorine - Preparation of a stock solution of free chlorine: First prepare a 1:10 dilution using a sodium hypochlorite solution containing approximately 6 - 14 % of active chlorine. For this pipette 10 ml of sodium hypochlorite solution into a calibrated or conformity-checked 100-ml volumetric flask and then make up to the mark with water for analysis.
