Abstract
Barium titanyl oxalate which is a precursor of barium titanate has been precipitated at pH 4~5 by a rapid addition of aqueous titanyl oxalate solution to artificial environmental water samples containing equivalent weight of <TEX>$Ba^{2+}$</TEX> ions. Quantitative recoveries of <TEX>$Cd^{2+}$</TEX> and <TEX>$Pb^{2+}$</TEX> from the water samples has been confirmed and found to be usable as a possible method of preconcentration for their determination.
