|Title:||Statistical Modeling Of Mixtures: A Tutorial Experiment Using Anodic Stripping Voltammetry [o Modelamento Estatístico De Misturas: Experimento Tutorial Usando Voltametria De Redissolução Anódica]|
De Andrade J.C.
|Abstract:||This work illustrates the modeling procedure for a solvent mixture using the simplex- centroid approach. The selected experiment was the optimization of the peak current observed in the direct determination of nickel by anodic stripping voltammetry (ASV) in a solvent mixture composed of N,N-dimethylformamide, ethanol and water. The text is presented in a tutorial way, showing in detail the several steps which must be followed in such a process. Since not all possible mixtures lead to a measurable instrumental response, pseudocomponents had to be used to rescale the experimental design. This also allows to show how to apply this tool, usually troublesome for non-specialists in mixture modeling procedures.|
