Sequential anaerobic and aerobic processes have been recommended to treat textile wastewater reliably. In this work, the focus was on finding an energetically more competitive system to remove… Expand
ESTERIFICATION OF OLEIC ACID IN A SEMI-BATCH BUBBLE REACTOR FOR BIODIESEL PRODUCTION
A semi-batch bubble reactor has been developed to produce fatty acid ethyl ester (biodiesel) by acid-catalyzed esterification of oleic acid with superheated ethanol vapor. In this paper, the effects… Expand
Chemometric Optimization of the Methodology for Determination of Molybdenum in Soils and Plants by Square Wave Adsorptive Stripping Voltammetry
- J. R. S. Carvalho, E. L. Reis, C. Reis, O. I. C. Damasceno, A. Neves, A. A. Matias
- Materials Science
The method is based on the adsorptive accumulation of complex molybdenum(VI) with 8-hydroxyquinoline, using voltammetric square wave cathodic stripping voltammetry. The composition and concentration… Expand
Catalysts for biodiesel based on Zn2-xCoxTiO4
Co-doped Zn2TiO4 powders were synthesized by the polymeric precursor method and characterized by thermal analysis, XRD, IR and UV-vis spectroscopy. Spinel phase Zn2-xCoxTiO4 was obtained, with small… Expand
