Identification of the Remediation of Contaminated Soil with Oil through the Flotation with Surfactant by Molecular Fluorescence Related to the Analysis of Multivariate Data

The countless cases of environmental contamination by oil activities have grown significantly over time. This implies the need to develop new techniques for recovery of the affected areas. The flotation technique has been highlighted for this purpose and associated with other techniques, either chemical, physical or biological, improves their efficiency, and consequently, the recovery of location will be effective. This work aims to evaluate the remediation of two horizons of Typic Quartzipisamment originating in Recôncavo, which were contaminated artificially with oil and recovered using flotation technique, and from the Fluorescence Induced LED (FIL), associated with Analysis Components (PCA). In the emission spectra showing a reduction of contaminants that fluoresce (flourescent intensity) of the horizon A and C contaminated for the remedied, length of 480 nm, the decrease in fluorescence intensity from 1600 to approximately 800 u. Through the association between the analytical technique used and the multivariate analysis was possible to distinguish the horizons contaminated with oil from the remediated horizons with the prepared solution.
