Abstract:

Injection of iron particles in contaminated sites is one of the most useful methods of land reclamation, for this reason, the study of iron particles diffusion in the poor is necessary to realize facilities increasingly performing. In this work, the behavior and spread of Carbon Iron particles were analyzed in a 2D confined aquifer model. Before to start the experiment, Carbon Iron features were analyzed by means of sedimentation tests and a viscometer. Initially, it was necessary to set up a 2D confined aquifer model and study its hydraulic conductivity. Two tracer tests were done for this purpose using a fluorescent dye called uranine. In the first tracer test, the concentration of uranine was in μg concentration and it was detected by optical fibers, the second one had a concentration in mg and the uranine was visible under neon lighting. After that, the features of the 2D model were known and the experiment phase started. Three different suspensions were injected to perform visual tests with a qualitative comparison. Initially, it was observed the behavior of a solution of water and uranine after that, a solution of Carboxymethyl cellulose and uranine was injected. In the end, 2g/l of Carboxymethyl cellulose and 20g/L of Carbon Iron was injected. After the Carbon Iron injection and the visual analysis, the 2D confined aquifer model was drained and a sample collection was carried out to obtain the concentration of the Carbon Iron components. This last part of the work allows a qualitative analysis and the possibility to understand the diffusion of the Carbon Iron in an aquifer.
