Title: Metodologia analítica para a determinação de sulfato em vinhoto
Keywords: sulfate
vinasse
anaerobic biodigestion
Issue Date: 30-May-2013
Publisher: Sociedade Brasileira de Química
Description: In this way it is very important to know the sulfate concentration in vinasse samples before to make the biodigestor design. A previous developed and indirect method (Anal. Chim. Acta. 1996, 329, 197), was used to determine sulfate in samples of vinasse, after previous treatments, done in order to eliminate organic matter with hydrogen peroxide 30% and concentrated nitric acid mixture (3:1), under heating. Interferent cationic ions were isolated by using ion exchange columns. The results obtained for some samples from Araraquara and Penápolis are here presented. The phosphate concentration was also determined.
