Abstract: Este capítulo avalia o comportamento de um solo tropical, e seu desempenho como barreira submetida à ação do fluxo de hidrocarbonetos da gasolina, pela interpretação do transporte de acordo com parâmetros físicos, químicos e aspectos micromorfológicos. Para isto a mineralogia foi caracterizada como também a influência da matéria orgânica (MO) considerando processos de adsorção dos hidrocarbonetos da gasolina e comportamento hidráulico em laboratório por meio da variação do gradiente hidráulico diante do fluxo da gasolina através de solo compactado. Dessa forma, este trabalho contribui para o entendimento da dinâmica do fluxo de compostos específicos: aromáticos, olefinas, hidrocarbonetos saturados e etanol, os quais são encontrados na gasolina tipo C brasileira (uma mistura complexa de compostos orgânicos). _________________________________________________________________________________________________ ABSTRACT
The aim of this study is to evaluate the behavior of a tropical soil, and their performance as liner against the flow of hydrocarbons from gasoline, by interpreting transportation according to physical and chemical parameters, as well as micromorphological aspects. For this characterized the mineralogy of the soil and the influence of his organic matter (OM), considering the adsorption processes of hydrocarbons from gasoline and hydraulic behavior in the laboratory by variation of the hydraulic gradient in front of the gasoline flow through compacted soil. This study also aims to contribute to the understanding of the dynamics of the flow through the soil of specific groups of compounds: aromatic, olephine, saturated hydrocarbons and the ethanol found in Brazilian type-C gasoline (a complex mixture of organic compounds).
