Аннотация:The potentialities of using silica gel modified with gold nanoparticles stabilized by chitosan are evaluated in the normal phase of HPLC as an example of the separation of aniline and pyridine derivatives, as well as triazole fungicides by elution with mixtures of hexane with isopropyl alcohol, isobutanol, or chloroform. The influence of the nature and content of the polar additive on the efficiency and separation selectivity of the column have been studied. The possibility of separating mixtures containing penconazole, propiconazole, diniconazole, difenoconazole, and aminopyridines is shown.
