Application
- 3,3′,5,5′-tetramethylbenzidine as a multi-colorimetric indicator of chlorine in water in line with health guideline values: This study focuses on using 3,3′,5,5′-tetramethylbenzidine as an indicator for the presence of chlorine in water, providing a method to ensure compliance with health guidelines through a visual and straightforward test (Palladino et al., 2020).
- Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests: This paper introduces a method for testing free chlorine concentrations in water at very low levels using lateral flow assays, which are crucial for monitoring water quality and ensuring safety standards (Schwenke et al., 2019).
- Some factors influencing the stability of Sterilox, a super-oxidised water: This article, while focused on the stability of Sterilox as a disinfectant, deals with the broader context of using chlorine solutions in settings requiring stringent sanitation measures, highlighting the importance of regular chlorine testing to ensure efficacy (Rossi-Fedele et al., 2011).
General description
(free and total chlorine) Method: colorimetric, DPD, with color-disk comparator 0.25 - 0.50 - 0.75 - 1 - 2 - 4 - 7 - 10 - 15 mg/l Cl MQuant®
Chlorine containing disinfectants are most widely used. They are applied particularly to disinfect drinking water and swimming pool water. The MQuant® Chlorine test (formally MColortest®) can be used for the determination of free and total chlorine.
This test can be used in
This test is not suited for seawater.
Method
In weakly acidic solution free chlorine reacts with dipropyl-p-phenylenediamine (DPD) to form a red-violet dye. In the presence of potassium iodide, also combined chlorine is measured in this reaction. The chlorine concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation.
The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments.
Using the refill pack 1.18326, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
