FIELD: chemistry.
SUBSTANCE: invention refers to method of standard sample O-alkylmethylphosphonates analysis for mass fraction of the ground substance to be used in ecological monitoring. Method consists in titration of their aqueous solutions by sodium hydroxide solution with using a potentiometric titration cell herewith automatically clamping an equivalence point in potential jump of titration curve.
EFFECT: method enhancement.
