General description

(free and total chlorine) with liquid reagent Method: colorimetric, DPD, with color-disk comparator 0.1 - 0.2 - 0.3 - 0.4 - 0.6 - 0.8 - 1.0 - 1.5 - 2.0 mg/l Cl₂ MQuant®
The MQuant® Chlorine test (formally MColortest®) can be used for the determination of free and total chlorine using liquid reagents.

The test can be used in
  • Swimming-pool water
  • Groundwater and surface water
  • 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. 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 1.14803 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.

How to Prepare a Standard for Free Chlorine Analysis

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.
