Determinação de complexos de urânio em solo usando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

This paper proposes to assess the lability of complexes of uranium in soil using the technique of Diffusion in Thin Films by concentration gradients (DGT) in the vicinity the Osamu Utsumi mine, located in the municipality of Caldas - MG. The technique is based on the 1ª Fick Law, where metal complexes diffuse through a gel, which in turn is adsorbed on a resin. The metals adsorbed are recovered by an analytical technique and quantified by optical emission spectrometer with plasma inductively coupled (ICP-OES) or mass spectrometry with inductively coupled plasma (ICP-MS)

Effect of the substitutional elements on the microstructure of the Ti-15Mo-Zr and Ti-15Zr-Mo systems alloys

Titanium alloys have excellent biocompatibility, and combined with their low elastic modulus, become more efficient when applied in orthopedic prostheses. Samples of Ti-15Mo-Zr and Ti-15Zr-Mo system alloys were prepared using an arc-melting furnace with argon atmosphere. The chemical quantitative analysis was performed using an optical emission spectrometer with inductively coupled plasma and thermal conductivity difference. The X-ray diffractograms, allied with optical microscopy, revealed the structure and microstructure of the samples. The mechanical analysis was evaluated by Vickers microhardness measurements. The structure and microstructure of alloys were sensitive to molybdenum and zirconium concentration, presenting α′, α″ and β phases. Molybdenum proved to have greater β-stabilizer action than zirconium. Microhardness was changed with addition of molybdenum and zirconium, having Ti-15Zr-10Mo (436 ± 2 HV) and Ti-15Mo-10Zr (378 ± 4 HV) the highest values in each system.
