Notes: Summary m-Ethyl phenoxyacetic acid is found to be a selective reagent for the estimation of zirconium. Even 2.2 mg of zirconia can be easily estimated. The composition of the precipitate is somewhat variable and so direct weighing is not possible. The difficulty is overcome by igniting the precipitate and weighing it as oxide. Zn, Ca, Ba, Be, Mg, UO2, Th, Mn, Co, Ni, Al, Ce, Ti, Fe, and Sn ions do not interfere in the precipitation of zirconium. Cr and V2O2 are coprecipitated with zirconium but they can be easily removed by double precipitation. Quantitative results are also obtained even in the presence of SO4.
