AATCC TM168-2023, Chelation Value of Polyaminopolycarboxylic Acids and their Salts: Copper PAN Method

 

1. Purpose and Scope

 

1.1 The active content of ethylenefiaminetetraacetic acid (EDTA), N-hydroxyethylenediaminetriacetic acid (HEDTA) and diethylenetriaminepentaacetic acid (DTPA) and their salts is usually expressed by the calcium chelation value (CaCV). This value indicates the amount of calcium (as calcium carbonate) which will be chelated by a known weight of chelating agent. This method excludes the effect of partially-substituted products.
