General description
Method: Colorimetric, with test strips, 3 - 10 - 25 - 50 - 100 - 250 - 500 mg/L (Fe²+), MQuant®The MQuant® test strips offer a very simple means of determining iron(II) in all aqueous media and on metal surfaces. They can thus be used to distinguish between ferrous and non-ferrous metals. Iron(II) ions react with 2,2′-bipyridine to form a red complex. The iron(II) concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. For a determination of Fe(III) it is necessary to treat the sample with Ascorbic acid first, to reduce Fe(III) to Fe(II). The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the iron concentration and a possible dilution factor prior to using a quantitative method such as a Reflectoquant® or Spectroquant® test.
