EDTA Tetra Sodium Salt (Trilon B) 25kg Bag

Trilon B Powder is an organic chelating agent used to control the concentration of metal ions in aqueous systems.

The active ingredient contained in Trilon B Powder is ethylenediaminetetraacetic acid (EDTA) or its salts.

The most important property of Trilon B is it’s ability to form water-soluble complexes with polyvalent ions,

(e.g. calcium, magnesium, lead, copper, zinc, cadmium, mercury, manganese, iron and aluminium) over a wide pH range from 2 to 13.5.

EDTA usually forms 1:1 complexes i.e. 1 mol of EDTA chelates binds to 1 mol of metal ions.  The metal ion is completely enclosed by the ligand.

These complexes remain stable, especially in alkali media and even at temperatures of up to 100^oc.

Trilon B has been shown to be very stable, compared with other organic complexing agents. Such as citric acid, tartaric acid and gluconates, especially at high temperatures.

Where as inorganic seqestring agents (e.g. phosphates), may hydrolyse at high temperatures Trilon B is stable, even when applying pressure at 200^oc.

The water however, evaporates at high temperatures.
