The 2.5th order differential pulse polarography has been investigated for titanium determination in natural water using a dropping mercury electrode. The optimum electrolyte system was found consisted of 0.02M mandelic acid and 4% potassium chlorate (PH=3), in which a well-defind neopolarogram of titanium was (observed. The negative peak potential E"np was at -0.87V (vs. SCE). A linear dependence of peak hight on titanium concentration over a range of 1×10^-10-1×10^-7g/ml was found. The method proved quite adequate in its sensitivity, rapidity and simplicity with recovery of 96-110% and minor inteference from a number of common ions.
