Leather — Determination of water-soluble magnesium salts — EDTA titrimetric method
| Published By | Publication Date | Number of Pages |
| ISO | 1984-02 | 8 |
Principle: Aqueous extraction of a test portion, followed by the evaporation and drying at 102 +/-2 degrees centigrade, and sulfating and ashing of the residue at 800 degrees centigrade, to yield the water-soluble inorganic matter. Treatment of the residue with hydrochloric acid, and titration with standard volumetric disodium ethylenedinitrilotetraacetate solution.
