"Determination Of Europium In Rare Earth Materials By Flow Injection Analysis"
Fenxi Shiyanshi 1988 Volume 7, Issue 10 Pages 4-6
Wu Xing

Abstract: In the flow injection system (diagram given), Eu(III) was treated with Zn - H+ in a Jones reductor for conversion into Eu(II) and mixed with a stream containing methylene blue, which was quantitatively reduced to its leuco form, and the decrease in absorbance at 673 nm was measured. For the determination of 400 and 800 µg of Eu2O3, recoveries were 92.8 to 105.8% and 94.5 to 103.2%, respectively.
