- Spectrophotometric Determination of Zirconium with Bromopyrogallol Red and Zephiramine
抄録
Zirconium formed a blue-violet complex with Bromopyrogallol Red in the presence of zephiramine in weakly hydrochloric acid solution. This complex showed an absorption maximum at around 639 nm, and the absorbance was constant over the acidity range of 0.18-0.28N (the final acidity). The proposed method covered a concentration range of 3-40 μg of zirconium in 25 ml of solution. The molar absorptivity was about 37000. The precisions in coefficient of variation were 2.0 and 1.2% for 10 and 30 μg, respectively, of zirconium. Many ions did not interfere with the experiment, but hafnium, vanadium, molybdenum, iron(III), mercury(II), fluoride, and phosphate interfered even when their amount was the same as that of zirconium. The permissible amount of iron (III) was increased by the addition of L-ascorbic acid.
