Abstract in Portuguese
Foi desenvolvido aqui um sistema de medida de polarização induzida no domínio de freqüência (0,13 Hz a 11,11 kHz) para ser utilizado em amostras no laboratório. O sistema apresenta versatilidade de construção, permitindo modificações internas de acordo com as necessidades experimentais e grande precisão mesmo em locais com condições desfavoráveis devido ao ruído ambiental. Testes são executados com amostras de areia misturadas com argila e contaminadas com gasolina pura, gasolina comum e etanol. De uma maneira geral os resultados mostram uma diferenciação entre as amostras contaminadas e as não contaminadas, principalmente na medida "Percentual de Efeito Frequência".

Abstract in English
This thesis presents the development of an Induced Polarization measurement system in the frequency domain (0.13Hz to 11,11 kHz) to be used in laboratory studies. The system presents construction versatility, allowing internal modifications in accordance with experimental necessities and high accuracy even in places with adverse conditions because of noise. Tests are executed with samples of a mix of sand and clay contaminated with pure gasoline, common gasoline and ethanol. In a general way, the results show a difference between the contaminated and non-contaminated samples, mainly in the measure of "Percent Frequency Effect".
