Use of the titanium(IV) chelate of salicylic acid for a selective absorptiometric determination of titanium.
Titanium(IV) forms a 1:1 chelate with salicylic acid in 40% aqueous ethanolic solution. The chelate is extractable into chloroform. A selective extraction method for the estimation of titanium in the presence of a variety of commonly interfering species is described. The addition of pyridine is found to increase the sensitivity and selectivity and makes it unnecessary to use alcohol in the extraction. The extracted species is a pyridine adduct of the titanium-salicylic acid chelate.
