Description
The spectrophotometric methods for the determination of microamounts of titanium have been based on the complexes with hydrogen peroxide', 1,2-dihydroxybenzene-3,5-disulfonate (tiron)2'3, chromotropic acid4'5 and diantipyrylmethane.6'' These methods have comparatively high selectivity but low sensitivity. Therefore, attempts have been made to enhance the sensitivity by combination with preconcentration methods for the determination of traces of titanium, including solvent extractiong-" and solid-phase extraction on supports such as membrane filter'2,'3, ion-exchange resin14 and naphthalene. l s The spectrophotometric, atomic absorption spectrometric and electroanalytical methods for many inorganic ions have been developed by using the collection process on chitin after their ions are converted into each suitable species such as colored metal complexes or anionic species. 16-30 Chitin, which is a natural amino polysaccharide and a hydrophilic polymer similar to cellulose, but is stable over a wide pH range of aqueous solution, has the excellent properties as the support for solid-phase extraction: namely, the collection and elution of species is rapidl6-'9, and its protonated acetylamino groups act as anion-exchangers for various type of anionic species in weak acidic medium.20-29 In this paper we report on the spectrophotometric determination of trace amounts of titanium(IV) following the preconcentration procedures as follows: first the collection as its anionic tiron chelate on protonated chitin, and second the elution with a small volume of ammonia buffer solution. The proposed method was applied to the determination of titanium in environmental samples.
