Method: reflectometric with test strips 0.5 - 20 mg/l Fe²⁺ Reflectoquant^®
The Reflectoquant test strips offer a very simple means of determining iron(II) in surface water, seawater, industrial water, wastewater and mineral water. Furthermore samples of food and preserves can be analysed. They can thus be used to distinguish between ferrous and non-ferrous metals. On the test strip, in acidic solution iron(II) ions react with a triazine derivative to form a red-violet complex that is determined reflectometrically on the RQflex. For a determination of Fe(III) it is necessary to treat the sample with Ascorbic acid first, to reduce Fe(III) to Fe(II). For pre-testing a sample in an economic and quick way to estimate the iron concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant test strips for iron Further quantitative determination methods can be found with our Spectroquant tests.
