Spectrophotometric determination of chromium in steel with 4-(2- thiazolylazo)-resorcinol (TAR) using microwave radiation

Journal of the Brazilian Chemical Society, 2004
A spectrophometric method for the determination of Cr(III) with 4-(2- thiazolylazo)-resorcinol was developed. Cr(III) slowly forms a red complex with TAR at pH 5.7.

Simultaneous Spectrophotometric Determination of Copper, Nickel, and Zinc Using 1-(2-Thiazolylazo)-2-Naphthol in the Presence of Triton X-100 Using Chemometric Methods [PDF]

Journal of the Korean Chemical Society, 2009
Multivariate models were developed for the simultaneous spectrophotometric determination of copper (II), nickel (II) and zinc (II) in water with 1-(2-thiazolylazo)-2-naphthol as chromogenic reagent in the presence of Triton X-100. To overcome the drawback of spectral interferences, principal component regression (PCR) and partial least square (PLS ...

Column Preconcentration and Second Derivative Spectrophotometric Trace Determination of Scandium in Standard Biological and Synthetic Samples Using 1-(2-Thiazolylazo)-2-naphthol

Analytical Sciences, 2000
Scandium has been preconcentrated from a large volume of its aqueous solution after solid phase extraction of its 1-(2-thiazolylazo)-2-naphthol chelate onto ammonium tetraphenylborate-naphthalene adsorbent in the pH range 4.0 - 5.8. The solid mass consisting of metal complex along with the adsorbent was dissolved in 5 ml of DMF and quantified by second
