1. Green Processing of Strategic Elements Based on Magnetic Nanohydrometallurgy
Magnetic nanohydrometallurgy (NHM) is a new process based on engineered superparamagnetic nanoparticles capable of performing as complexing agents for extracting and recovering strategic metals from mineral sources and urban wastes, as well as for removing hazardous elements from contaminated water. Its principles and application are reviewed in this paper.

2. ESTUDO COMPARATIVO ENTRE EXTRAÇÃO SOXHLET E ULTRASOM PARA DETERMINAÇÃO DE HIDROCARBONETOS POLICÍCLICOS AROMÁTICOS EM SEDIMENTOS DO ESTUÁRIO DO RIO SERGIPE POR CROMATOGRAFIA A GÁS ACOPLADA A ESPECTROMETRIA DE MASSAS. / COMPARATIVE STUDY OF EXTRACTION SOXHLET AND ULTRASOUND DETERMINATION FOR OIL POLYCYCLIC AROMATIC SEDIMENTS SERGIPE RIVER ESTUARY BY GAS CHROMATOGRAPHY MASS SPECTROMETRY ATTACHED.
Polycyclic aromatic hydrocarbons (PAHs) are compounds that can be found in environmental compartments such as atmosphere, soil, sediment and water. Throughout bioaccumulation, they can also be incorporated into vegetables and animals tissues. They are mainly originated from anthropogenic sources such as fossil fuels and biomass burnings. Due they potential t

5. Reator eletroqu¡mico de bancada para remoção de íons de metais a partir de efluentes industriais / Removing Metal Ions from Industrial Effluents
An electrochemical reactor, with the aim of recovering metallic ions from waste water, was designed, built and evaluated in laboratory scale. The working conditions concerning to the ion concentrations were based in real operational data. Thus, solutions containing 15,900 ppm Cu2+ ions (0.25 M) were electrolysed with the purpose of obtain a final concentrati
