Electrolyte Ph

N-hydroxyethyliminodiacetic acid (HIDA) has been used for the optimization of the isotachophoretic separation of alkali and alkaline earth metal cations. The required separation effect appears at the leading-electrolyte pH = 6-7. The separation of K+, Na+, Li+, Ba2+, Sr2+, Ca2+, and Mg2+ has been achieved using HIDA as the complexing co-counterion. In the dependence on the leading-electrolyte pH and on the HIDA concentration in it various migration sequences can be achieved in the isotachophoretic steady-state. Alkali metal cations present in the model mixtures were determined in the concentration range (1-125) . 10-5 mol l-1 with the relative standard deviation that was in most cases less than 1%. Detection limits for individual ions (for the injected sample volume of 25μl) were within the limits of (6.4-18). 10-6mol l-1. The separation of the alkali metals in mineral and drinking water and in the lyophilized blood demonstrate the practical use of the agent under study in the ITP analysis

First Time

New crown-containing imines of 1-hydroxyanthraquinone with chlorine and fluorine atoms in the anthraquinone nucleus were synthesized. For the first time, the thermal and photochemical stages of synthesis are carried out in the solid state (without a solvent). The features of complexation of new chemosensors with cations of alkaline and alkaline earth metals were studied by spectrophotometry. It is shown that the introduction of halogen atoms in the anthraquinone nucleus leads to a significant spectral response. The obtained compounds are tested as components of test systems for visual determining the presence of alkaline earth metal cations in aqueous media.
