General description
Method: titrimetric with dropping bottle MColortest®
The test measures the content of salts of the alkaline earth metals calcium, magnesium, strontium and barium in groundwater and surface water, drinking water, mineral water and boiler water.
This MQuant® Total Hardness test (formally MColortest®) is suitable for the titrimetric determination using a convenient dropping bottle. It can be used in:
Method
Calcium and magnesium ions react with an indicator to form a red complex compound. The indicator is released from this compound by titration with a solution of ethylenedinitrilotetraacetic acid disodium salt dihydrate (Titriplex® III). At the titration end-point the color changes to green. The total hardness is determined from the consumption of titration solution.
- Groundwater, surface water, and seawater
- Waters from aquaculture
- Drinking water and mineral water
- Swimming-pool water
- Boiler water
- Industrial water
