The determination of boron in food and seed by spectrophotometry using a new reagent 3,4-dihydroxyazomethine-H


, : The determination of boron in food and seed by spectrophotometry using a new reagent 3,4-dihydroxyazomethine-H. Food Chemistry 94(2): 310-314

A new sensitive and selective reagent, 3,4-dihydroxyazomethine-H, was studied for spectrophotometric determination of boron in food and seed. Boron (III) reacts with 3,4-dihydroxyazomethine-H to form a 1:2 yellow complex in an ammonium acetate solution of pH 8.0, which has a maximum absorption peak at 430 nm. Under the optimal conditions, Beer's law was obeyed over the range 0-20 micro g of boron (III) in 25 ml of solution.
