S.2012-12-10T20:26:09Z2012-12-10T20:26:09Z19930026-3672http://www.repositorio.ufba.br/ri/handle/ri/7391v. 111, n. 1-3Texto completo: acesso restrito. p. 119-125The reaction between titanium(IV) and 2-(2-thiazolylazo)-p-cresol- (TAC) in aqueous methanol media at apparent pH 4.0-5.6 results in a intensely coloured complex that is stable for at least 2 h. The combining ratio is 1 : 1 cation : TAC. Beer's law is obeyed up to 5.0 #g/ml titanium(IV) at 580 nm. The apparent molar absorptivity at 580 nm is 9.82.103 1.mole-l.cm -~ and the detection limit obtained was 5 ng/ml titanium(IV). A spectrophotometric method for the simultaneous determination of titanium and iron with TAC is proposed.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2012-12-10T20:26:09Z No. of bitstreams: 1 ccc.pdf: 366458 bytes, checksum: c215d50a0b1c4f4696dcf377de542378 (MD5)Made available in DSpace on 2012-12-10T20:26:09Z (GMT).
