MN VISOCOLOR® ECO test kit potassium, 2-15 mg/l K+

VISOCOLOR® ECO Potassium Features: • Determination of potassium as turbidity measurement • Potassium reacts with sodium tetraphenylborate to form a precipitate. • Under defined conditions this turbidity can be used for concentration measurements. • Turbidities interfere and have to be filtered prior to the test. • Good reproducibility is obtained for drinking, surface and ground water. • For polluted waste waters low potassium values are measured. • The natural potassium content in ground water is generally about 1 – 2 mg/l K+. • Higher values may indicate faecal contaminations, but can also originate from potassium fertilisers. • For the growth of plants and animals potassium is an essential factor. • Especially in agriculture the determination of potassium therefore gains increasing importance.
