Simultaneous Injection Effective Mixing Flow Analysis System for Spectrophotometric Determination of Palladium in Dental Alloy and Catalyst
نویسندگان
چکیده
A simultaneous injection effective mixing flow analysis (SIEMA) system was proposed for the spectrophotometric determination of palladium. The determination of palladium was based on its complexation reaction with 2-(5-bromo-2-pyridylazo)-5-[N-n-propyl-N-(3-sulfopropyl)amino]aniline (5-Br-PSAA) to form a blue complex, which has an absorption maximum at 612 nm. The analytical performances of the proposed SIEMA method were superior to a conventional FIA method using 5-Br-PSAA in several parameters, such as reagent consumption, waste volume and analysis time. The SIEMA method was applied to the determination of palladium in dental alloy and hydrogenation catalyst.

Solid phase spectrophotometry (SPS) provides effective methods to combine metal ion preconcentration and their spectrophotometric determination, by integrating the formation of colored complexes and their fixation on the surface of a solid support placed inside the measurement cell. The coupling between flow injection analysis (FIA) and SPS (FI-SPS) makes it unnecessary to reach equilibrium con...
