Última Dendritic Gold Nanoparticles Towards Transparent and Electroactive Electrodes Anais da ABC (AABC) IOST,RODRIGO M.; MARTINS,MARCCUS V.A.; CRESPILHO,FRANK N.. Abstract: The combination of UV-visible absorption and electrochemical experiments (spectroelectrochemistry) enables to obtain highly specific spectroscopic information (in situ and operando) from modified surfaces. However, such application can be limited by the self-absorbance, for example, when metallic nanoparticles are present on modified surfaces. Indium-tin oxide onto glass (ITO) is a typical electrode commonly used for spectroelectrochemistry; ITO is an oxide-based semiconductor, and in numerous applications it is necessary to promote the modification of the electrode surface without significant loss of transparency. Here, we report a simple strategy to obtain ITO electrodes modified with self-assembled polyelectrolytes and active dendritic gold...

The performance of axial view ICP OES and ICP-MS techniques were compared through the determination of As, Fe, Mn, Pb, Sb and Sn in electrolytic copper. Samples were prepared by two procedures: 1. Total dissolution with 5 % v/v HNO3 and 2. Dissolution with 1.4 % v/v HNO3 plus 2.0 % v/v H2SO4, followed by separation of the Cu by electrodeposition. The methods were applied for the analysis of standard copper solutions, using calibration against aqueous solutions with or without the addition of Cu. The results obtained by the two techniques were similar, but the separation of Cu from the sample matrix proved to be more adequate for practical reasons.
