Method for test determination of propylgallate includes sampling, its dissolution in organic solvent, extraction, interaction of propylgallate with terbium (III) ions and measurement of analytical signal. Propuylgallate undergoes interaction with ions of ternium (III) modified on surface of sorbent Sephadex G-150, in presence of &bgr;-cyclodextrine and acetate buffer solution at pH=4.5. |
