Utilização de regressão multivariada para avaliação espectrofotométrica da demanda química de oxigênio em amostras de relevância ambiental

Abstract: Recebido em 31/8/04; aceito em 23/2/05; publicado na web em 30/6/05 USE OF MULTIVARIATE REGRESSION IN SPECTROPHOTOMETRIC EVALUATION OF CHEMICAL OXIGEN DEMAND IN SAMPLES OF ENVIRONMENTAL RELEVANCE.In this work, a partial least squares regression routine was used to develop a multivariate calibration model to predict the chemical oxygen demand (COD) in substrates of environmental relevance (paper effluents and landfill leachates) from UV-Vis spectral data. The calibration models permit the fast determination of … Show more
