Abstract
ABSTRACT A new rapid, high sensitive and selective on-line microwave flow injection method has been developed for the determination of micro-amounts of ruthenium, based on its catalytic effect on the oxidation of dibromocarboxyarsenazo (DBM-AsA) by potassium periodide in acidic medium. The assay is performed in a microwave-induced flow injection analyzer by measuring the absorption of DBM-AsA at 538 nm spectrophotometrically.
