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
