[ 1 ] - Janus Green Dye as a New Reagent for Catalytic Kinetic Determination of Zirconium in Ceramic Materials

A new catalytic kinetic spectrophotometric procedure for determination of trace quantities of zirconium was proposed. Janus Green was oxidized by potassium bromate and zirconium catalyst which then converted to a colorless product in acidic media. Reaction rate was monitored spectrophotometrically at 606 nm. It relies on the linear relationship between the absorbance difference (ΔAt) and Zr(IV)...
