Abstract: | The reactions of a number of natural organic reducing agents with a copper(II) complex with tetrabenzob, f, j, n]1, 5, 9, 13]tetraazacyclohexadecine adsorbed on silica were examined. A solid-phase reagent was proposed for the sorption–spectrophotometric determination of Analgin and ascorbic acid (c
min= 0.91 and 0.06 mg/L, respectively) and for the visual test determination of the above compounds (c
min= 0.50 and 0.025 mg/sample, respectively). |
