m-Cresoxyacetic Acid, a Selective Reagent for Zicronium

Abstract

D EAGENTS for the determination of zirconium are many, but *few are selective. The best known is mandelic acid, recommended byKumins (£). To this may be added m-cresoxyacetic acid,•-0-CH2COOH, a reagent that is easily pre-CH3 pared and purified (I). From solutions 0.20 to 0.25 N in hydro-

“…In the presence of chromium, vanadium, tin, and titanium, a second precipitation is necessary. m-Cresoxyacetic acid w-as recommended as a specific reagent for zirconium (155).…”
