New Chromogenic Reagent Arsenazo DBF Used for Spectrophotometric Determination of Rare Earth Elements

Abstract

Abstract: The present paper reports the synthesis of arsenazo DBF, its characteristic, its reaction with rare earths ions and its application to the selective determination of cerium-group in aluminium-alloy. Arsenazo DBF, 2-(2-arsonophenylazo)-7-( 2, 6-dibromo-4-formylphenylazo )-1,8-dihydroxynaphthalene-3,6-disulfonic acid reacts with cerium-group rare earths to form blue-green colour complexes in NaAe-HCl aqueous solution at pH 2.2.The absorptive peak is at 630 nm. The molar absorptivity of La complexe is 1.3×10⁵ L·mol^-1·cm^-1. Beer's law is obeyed over the concentration range 0～12μg/25mL of La.

Key words: Arsenazo DBF, Rare earths, Spectrophotometry
