The influence of ligand adsorption and concentration,supporting electrolyte and pH on the voltammetric response wasstudied. From these results the stoichiometric ratio of the complexand the value of its corresponding formation constant were determined.Under optimized chemical and instrumental conditions limitsof detection (3s) of 7.0 ´ 109 M and 4.0 ´ 109 M were obtained forSCV and SWV, respectively, using a deposition time of 90 s. The relativestandard deviations (n = 21) were 3.3 and 4.8 % for a 1.5 ´107 M In(III) concentration. The results of an analysis carried out forindium present in aluminum alloys were in good agreement withthose obtained using ICP-AES as an alternative method. 2001 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47545104 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.1 Vol.45 |
