Spectrophotometric determination of beryllium

Microchimica Acta Aims and scope Submit manuscript

Summary

A spectrophotometric method for determination of beryllium inμg quantities is described which is based on color reaction between beryllium and rufigallol having maximum absorption at 530 nm. Comparing various solvents, the suitable medium found is DMSO-H2O (3 ∶ 2). Interference of Al, Zr, Th, Hf and many other cations have been removed by solvent extraction of their oxinates with chloroform.

Zusammenfassung

Eine spektrophotometrische Bestimmungsmethode für Mikrogrammmengen Be wurde beschrieben, die auf der Farbreaktion mit Rufigallol mit einem Absorptionsmaximum bei 530 nm beruht. Als geeignetes Medium erwies sich Dimethylsulfoxid in Wasser (3 ∶ 2). Störende Kationen wie Al, Zr, Th, Hf und viele andere werden in Form ihrer Oxinate mit Chloroform extrahiert.
