说明
一般描述
Acid capacity to pH 8.2 ａnd pH 4.3 Method: titrimetric with titration pipette MQuant®
The alkalinity is an important parameter for the assessment of the surface-water quality ａnd the corrosive behaviour of water as well as for water ａnd wastewater treatment. This MQuant® Alkalinity test (formally MColortest®) is suitable for the titrimetric determination using a graduated syringe.

Method
One sample (sample A) is titrated with hydrochloric acid against phenolphthalein until it becomes colorless (at pH 8.2), while a second sample (sample B) of the same water is titrated against a mixed indicator until its color changes to red (at pH 4.3). The values for KS8.2 ａnd KS4.3 are determined from the corresponding consumption of titration solution.

The test measures alkalinity in e.g.
Groundwater ａnd surface water, seawater
Drinking water ａnd mineral water
Industrial water, prozess water, ａnd wastewater
Boiler water
Aquarium water ａnd waters from aquaculture
Swimming-pool water
