Catalytic current polarographic determination of traces of titanium in water after preconcentration by coflotation

A new method is reported for the-determination of trace levels of Ti(IV) in water by cofiotation and polargraphy. Ti(IV) is preconcentrated and separated by cofiotation using aluminium hydroxide as coprecipitant and sodium oleate as surfactant. Polarographic determination of titanium content in the froth is based on the catalytic wave ofTi(IV) in the presenceof chlorate and oxalate. The effect ofvarious cations and anions on the fiotation and determination of titanium has been investigated. The method has been applied to estimation of titanium in natural fresh water samples
