Description

Description

Set for determination of calcium and magnesium hardness in waste water. Suitable for the Titralab AT1000 series of automatic titrators, models AT1112, AT1122 and AT1222.

Hach Titrator Kits contain all the elements except reagents so that each user can set up and run their tests quickly and easily. Each kit is specially designed for unique parameters to provide accurate and reproducible measurements.

Method for determination of hardness (Ca and Mg) based on ISO 6059: 1984

Water hardness is the sum of the calcium and magnesium ions present in the water. The above standard lays down a titration with EDTA at pH 10.00 using NH4Cl / NH4OH buffer and colorimetric determination of the equivalent point.

The method also uses EDTA titration with potentiometric equivalent point determination using an ion-selective electrode for calcium determination. Instead of NH4Cl / NH4OH buffer, a mixture of TRIS and acetylacetone is used. This buffer solution separates calcium and magnesium using the ISE calcium electrode.
