| dc.description.abstract | Titanium (IV) has been found to react with N'·Hydroxy.N',N2.diphenylbenzamidine ( HDPBA) and thiocyanate to form an orange colored mixed ligand complex which was quantitatively extractable into toluene from 0.5 . 0.25 M HCl solutions. The complex exhibited an absorption maximum in the visible region at 400 nm with a molar absorptivity 0[20,000 M" cm" and the system obeyed Beer's law in the concentration range of 0.29·3.6 ppm of Ti. The composition of the complex has been established spectrophotometrically to be 1: 1:2 (Ti: SCN:HDPBA). The effects of foreign ions and several other experimental variables have been studied to establish the optimum conditions for the extraction and determination of titanium. On the basis of these studies a new method has been developed for the determination of titanium (IV) with HDPBA and thiocyanate by solvent extraction and spectrophotometry. The method is precise, fairly sensitive and highly selective and free from rigid control of experimental variables, Moreover, the method has been successfully applied to the determination of titanium in several synthetic samples corresponding to titanium containing ores, minerals and alloys | en_US |
