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