Determination of Germanium with Phenylfluorone by #beta#-Correction Sectrophotometry

摘要

The determination of trace amount of germanium with phenylfluorone using #beta#-correction new spectrophotometry was studied. At pH 4.5, the germanium complex exhibits an absorption maximum at 540 nm, whereas that of the reagent is an 510nm. Beer's law was obeyed over the concentration range of 0-12.5 #mu#g of germanium per 25 mL of final solution. The method has been applied to the determination of trace amount of germanium in water and coal with satisfactory results
