“…During the spectrophotometric determination of Ti (IV), a number of organic chromogenic reagents, such as o-carboxyphenylfluorone [19], ponceau S [18], diantipyrylmethane [20], resacetophenone p-hydroxybenzoylhydrazone [24], thiocyanate [25], 2,3-dihydroxynaphthalene [26], 3,5,7,2',4'-penta hydroxy flavone [27], 5-(2', 4'-dimethylphenylazo)-6-hydroxypyrimidine-2,4-dione [28], bromopyrogallol red [29] and o-chlorophenylfluorone [30], have been used to produce an intense color for absorbance measurement. Most of these reagents are expensive, harder-to-obtain and environmental-unfriendly.…”

Introduction of titanium oxides with high permittivity on etched aluminum foils' surface has been successfully utilized to increase specific capacitance of anode foils for aluminum electrolytic capacitors. In order to quantify the concentration of titanium (IV) on the etched aluminum foil precisely, a simple and rapid spectrophotometric procedure has been developed. After optimizing a series of variables including absorbance wavelength, concentration of nitric acid, concentration of hydrogen peroxide, nitration time and developing time, analytical precision and accuracy were tested by using standard working solution containing known amount of titanium (IV). The results showed that Lambert-Beer's law was obeyed in the range of 0.01 to 3.00 mmol•L −1. The relative standard deviation (RSD) ranged from 0.67% to 1.09% (n = 6), and the recovery was between 99.17%-100.03%. Investigation on effect of Al 3+ ion indicated that there was no interference in the absorbance of titanium (IV) at 410 nm. The proposed procedure was applied to real samples for the determination of titanium (IV), and the results were in a good agreement with the values certified by inductively coupled plasma-atomic emission spectrometry (ICP-AES).

“…Spectrophotometric techniques remain a frequent choice for routine analyses as they provide simple, accurate and inexpensive solutions when compared to other methods. Several spectrophotometric methods were reported in the literature for the analytical determination of titanium(IV) [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. These methods adopt relatively complicated and time sensitive procedures or involve sensitive extraction steps prone to contamination at any stage of the analysis and hence require skilled analysts [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

A new, rapid, simple, precise and extraction-free spectrophotometric method is proposed for the micro determination of titanium(IV) employing N'-(2-hydroxybenzylidene)- 3-oxobutanehydrazide as a reagent. Under the optimum conditions established, the absorbance was found to increase linearly with the concentration of titanium(IV) in the range 1.757 to 17.57 μg mL−1. The method parameters such as the molar absorptivity, Sandel sensitivity, stoichiometry of the complex, method detection limit and limit of quantification were reported. The reproducibility of the method was excellent and recoveries reported were ranging from 102 to 104%. The proposed method can be readily applied for the determination of titanium(IV) in synthetic mixtures and alloys
