REAGENT FOR ALIPHATIC AMINES AND THEIR POLYAMINOPLICARBONE DERIVATIVES (COMPLEXES) Russian patent published in 2017 - IPC G01N21/78 

FIELD: chemistry.

SUBSTANCE: reagent consists of two components: a complexing ion based on polyvalent elements in lower oxidation states, such as Co²⁺, Mn²⁺, Ce³⁺, Forming stable complexes with nitrogen-containing ligands, and an oxidizer based on 18-tungsten, molybdo-2-phosphates of composition M₆[P₂W_18-nMo_nO₆₂]⋅xH₂O, where M=Li, Na, K, NH₄; n=0-18; x=10-12.

EFFECT: invention allows to determine the polyaminopolycarboxylic amines and their derivatives in the presence of compounds that absorb light in the medium and short-wave part of the spectrum.
