Method for ionometric determination of boron relates to analytical chemistry and can be used in plant, scientific-research and chemical-analytical laboratories. The method includes transformation of compounds of boron to form of tetrafluoroborate ions by means of acid fluoride-containing solutions and following measurement of activity of ions of tetrafluoroborate with use of chemical sensor. As electrode-active substance of chemical sensor one uses ion associate 2-(N-ethylcarbazole -3)-ethynil-1,3,3 trimethyl-3H-indole tetrafluoroborate with respective component ratio. The method provides increase of selectivity of electrodes, simplification of process ofsamplepreparation and decrease of time of analysis. |
