Abstract
This study addressed the use of conventional and vegetable origin polyurethane foams to extract C. I. Acid Orange 61 dye. The quantitative determination of the residual dye was carried out with an UV/Vis absorption spectrophotometer. The extraction of the dye was found to depend on various factors such as pH of the solution, foam cell structure, contact time and dye and foam interactions. After 45 days, better results were obtained for conventional foam when compared to vegetable foam. Despite presenting a lower percentage of extraction, vegetable foam is advantageous as it is considered a polymer with biodegradable characteristics.

Despite presenting a lower percentage of extraction, vegetable foam is advantageous as it is considered a polymer with biodegradable characteristics
In comparison of the standard curve to the curves presented after 45 days in contact with the foams, extraction occurred in both cases, with a greater proportion of extraction by conventional foam
Summary
This study addressed the use of conventional and vegetable origin polyurethane foams to extract C. After 45 days, better results were obtained for conventional foam when compared to. Despite presenting a lower percentage of extraction, vegetable foam is advantageous as it is considered a polymer with biodegradable characteristics. Introduction agents are resistant to biodegradation due to the presence of substituted chemical groups that are difficult to remove by All existent animal and vegetable life on the Earth are biological treatment, and their photochemical degradation constituted of great percentages of water. 60 to in aqueous solution which may occur in lakes and rivers, is 70% of the weight of a human being is constituted of water a very slow process because synthetic dyes are designed to molecules. The colored effluents, even becoming scarce in various places on earth, given that only in concentrations below 1 ppm are visible in an aqueous
