Abstract
A highly stable and bright lemon-yellow titanium tungstate has been synthesized by mixture of 0·3M-sodium tungstate with 0·3M-titanium chloride in the volume ratio 1 : 1 at pH 1·0. The effect of drying temperatures on the ion-exchange capacity, the chemical stability, and the Kd values of some metal ions have also been studied. The titanium : tungsten ratio in the sample (dried at 80°) was found to be 1 : 1·1. Its analytical importance has been shown by the quantitative separation of Ga3+ from Fe3+, In3+, and Al3+. A previously prepared1 titanium tungstate (sample II) has been used for the quantitative separation of lead from numerous metal ions.Keywords
