Abstract
DIVERSAS BACTERIAS QUIMIOLITOTROFAS CATALIZAN LA OXIDACION DE SULFUROS METALICOS, POR MECANISMOS DIRECTOS O INDIRECTOS, Y PRODUCEN ACIDO, ES DECIR H2SOA, SALES METALICAS SOLUBLES CON MUCHA MAYOR RAPIDEZ QUE POR OXIDACION QUIMICA. LA ELIMINACION DE LAS BACTERIAS INHIBIRIA LA FORMACION DEL ACIDO. LA PRODUCCION NATURAL DE ACIDOS ES PERTURBADORA EL LAS MINAS PUES SE PRODUCE AGUA ACIDA QUE DAÑA EL AMBIENTE. UN METODO EFECTIVO DE DISMINUIR O ELIMINAR ESTA PRODUCCION DE AGUA ACIDA ES APLICAR UN BACTERICIDA TAL COMO UN TENSIOACTIVO ORGANICO BIODEGRADABLE QUE CON BAJOS VALORES DE PH SON BACTERICIDAS, Y ASI INHIBIR QUE LAS BACTERIAS CATALICEN LOS SULFUROS METALICOS. EL LUGAR AFECTADO PUEDE TRATARSE CON EL TENSIOACTIVO QUE DA RESULTADO DURANTE ALGUNOS MESES. UNA SOLUCION PARA UN AÑO O MAS SE EMPLEARA LA COMPOSICION DE ESTA INVENCION, EN LA QUE UNA MATRIZ HETEROGENEA CONTIENE UNA PARTE TERMOPLASTICA Y OTRA DE TENSIOACTIVO ORGANICO. CON CANTIDADES ADECUADAS SE LOGRA UNA POROSIDAD APROPIADA PARA UNAACCION PROLONGADA. SE DESCRIBE UN METODO PARA OBTENER LA MATRIZ HETEROGENEA MEZCLANDO EN SECO LOS COMPONENTES Y AÑADIENDO DESPUES LAS BACTERIAS Y MEZCLANDO.
