The present work proposes the application of the 4-Hidroxy-3-(2-hydroxynaphtylazo)-benzenesulphonic acid (C.I. 15670), Alizarine Violet N (AVN), as a reagent for direct aluminium determination using molecular absorption spectrophotometry in the presence of tensoatives. Al(III) cation reacts with AVN in pH 9.4, forming a red complex, stable for at least 24 hours, with absorption minimum at 607nm and, against a reagent blank, (ecomplex - ereagent) = -2.71x104 L.mol-1.cm-1. The reaction occurs in the presence of a Triton-X100 and CTAB tensoatives mixture, in the presence of EDTA. Al(III) determination is possible in the linear range of 50 up to 400ng.mL-1, with a detection limit of 41 ng.mL-1.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-19T11:36:41Z No. of bitstreams: 1 2112.pdf: 54494 bytes, checksum: 06d165d609fe9fbf8b90ef447302c415 (MD5)Made available in DSpace on 2011-12-19T11:36:41Z (GMT).
