Abstract
Titanium (IV) oxalate complexes are reduced catalytically in the presence of chlorate and this gives rise to an13; enhancement in sensitivity . Experimental conditions such as acid strength and the concentrations of chlorate,13; oxalate etc . were standardized to extend the linearity of calibration graph to low titanium concentrations. The13; interfering effect of other metal ions like Fe(III), Mo(VI), Cu(II), Bi(III), Pb(II), Cd(II), Ni(II), Cr(III), Cr(VI) and Zn(II) on the catalytic current of Ti(IV) was investigated . The detection limit for the determination of Ti(IV) by this method was found to be 5 ng nil-t.
