General description
Chloride is found in the earth´s crust and can therefore also be found in all natural waters at some concentration. This MQuant® Chloride test (formally MColortest®) is suitable for the titrimetric determination using a convenient dropping bottle.
Method
In nitric solution chloride ions are titrated with mercury(II) nitrate solution against 1,5-diphenylcarbazone as the indicator, forming slightly dissociated mercury(II) chloride in the process. At the titration end-point, excess mercury(II) ions react with the indicator to form a blue-violet complex. The chloride concentration is determined from the consumption of titration solution (mercurimetric determination).
The test can be used in
This test is suitable to detect chloride interferences which are a mayjor reason for wron COD readings. Therefore it can serve as pretest for COD measurements with e.g. our Spectroquant® COD cell tests for seawater/samples with high chloride content 1.17058 and 1.17059.

The test can be used in
- Groundwater, surface water, and seawater (after dilution)
- Waters from aquaculture
- Drinking water and mineral water
- Water for concrete in the construction industry
- Industrial water and wastewater
- Boiler and boiler feed water, cooling water
- Swimming-pool water
- Food after appropriate sample pretreatment
- Soils and fertilizers after appropriate sample pretreatment
