1. THE EFFECT OF DIFFERENT METALLIC ELECTRODES ON THE ELECTROCOAGULATION OF OILY WASTEWATER / O EFEITO DE DIFERENTES ELETRODOS METÁLICOS NA ELETROCOAGULAÇÃO DE EFLUENTES OLEOSOS
In the present work, electrocoagulation process (EC) with aluminum and iron as materials for anode and stainless steel as cathode, under different operational parameters, such as: initial concentration of oil, distance between electrodes, area-volume relation (SA/V) and current density, were examined in a systematic manner. Chemical oxygen demand (COD) and t

2. Caracterização de escorias e recuperação do silicio / Characterization of slag and recovery of the silicon
Metallurgieal Grade Silicon (MGSi) is produced by a well-established industrial process that consists of the carbo-reduction of quartz in a submerged are fumace under high temperature. The process is an intensive energy consumption method (13 - 15 kWh to each kilogram of produced MGSi). After tapered, the MGSi is submitted to some purification stages in orde

3. Dissolução eletrolítica de ligas de alumínio em cavacos e determinação dos elementos constituintes por espectrometria de emissão atômica com fonte de pasma (ICP-OES) / Electrolytic dissolution of aluminum alloys (Chip form) and multi-element determination by inductively coupled plasma optical emission spectrometry (ICP-OES)
Several aluminum alloys with different chips size were dissolved using aqua regia (HCl:HNO3,3:1). The residues of the dissolution procedure were either rejected or used in silicon volatilization with hydrofluoric acid before determination of Fe, Cu, Mn, Mg, Cr, Ni, Zn, Pb, Sn, Ti and Zr by ICP-OES. The influence caused by crescent amounts of aluminum in the
