General description

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 in•Groundwater and surface water•Drinking water and mineral water•Waters from aquaculture•Wastewater•Electroplating wastewater•Disinfectant solutionsThis test is not suited for seawater.MethodIn 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 1.14977 the original test kit can be used for a very long time, making it a particularly economical and ecological system.

(free chlorine) Method: colorimetric, DPD, with color-disk comparator 0.25 - 0.50 - 0.75 - 1 - 2 - 4 - 8 - 10 - 15 mg/l Cl MQuant^®
