Description

The Macherey-Nagel Visocolor ECO Potassium Water Test is a colorimetric water test for determining the potassium content of a water sample. Potassium is one of the most important water plant nutrients and should therefore be present in sufficient concentration in the water. This water test is used for visual determination, but can also be used for photometric measurement with a compact photometer from Machery-Nagel.

Potassium forms a precipitate with sodium tetraphenylborate. Under special conditions, this turbidity can be used for concentration determination. Turbidities interfere with readability and should be filtered first. Good reproducibility is achieved in drinking, surface and ground waters. Polluted waste water leads to lower results.
