CSA Group Sodium chloride for industrial use - Determination of calcium and magnesium contents - EDTA complexometric methods ISO 2482:1973

Description
The method is applicable to water-soluble salts for contents greater than 0,001 % (m/m). In a special case, the determination of ions in a principal solution prepared in an acid medium is pooible. The principle consists in dissolution of a test portion and separation of insoluble matter. Titration of the filtrate obtained according to ISO 2479 using disodium ethylendiamintetraac etate (EDTA) in the presence of glyoxal-bis-(2-hydro xyanil) (GBHA) and mordant black 11 (Cl 14645) respectively as indicators.
