FIELD: chemistry.
SUBSTANCE: sodium thiosulphate is added to a solution containing iron (III) until achieving background concentration thereof of 0.06 mol/l, followed by ionometric determination of iron (III) in form of an anionic complex using an ion-selective electrode with a liquid membrane.
EFFECT: invention increases sensitivity and selectivity of analysis and widens the range of measured iron concentrations.
