Si nos preguntan qu\u00e9 contaminantes del agua conocemos, la mayor\u00eda pensamos en aceites, productos qu\u00edmicos, pl\u00e1sticos, etc., pero en los hogares tambi\u00e9n a\u00f1adimos al agua otro tipo de sustancias de forma cotidiana. Es el caso de los productos que usamos en la ducha, o para lavar la ropa o los restos de medicamentos que eliminamos con la orina. A veces, las plantas de tratamiento de aguas residuales no son capaces de eliminarlos por completo y, a\u00fan en peque\u00f1as concentraciones, pueden afectar a los ecosistemas acu\u00e1ticos.<\/p>\n

Investigando como eliminarlos, la Universidad Rovira i Virgili de Tarragona y la Universidad Internacional de Florida han descubierto un \u201csencillo\u201d sistema para atrapar estos contaminantes, una tela de algod\u00f3n. \u00bfCu\u00e1l es el secreto? La tela lleva impregnados unos\u00a0pol\u00edmeros <\/a>con propiedades similares a las de los contaminantes. Cuando el agua atraviesa la tela, los pol\u00edmeros, por afinidad, detectan los contaminantes y los \u201csecuestran\u201d, quedando as\u00ed retenidos en las fibras del tejido.<\/p>\n

Este sistema supone grandes ventajas debido a su gran facilidad para extraer los contaminantes, ya que bastar\u00eda con meter la tela en un peque\u00f1o contenedor con disolvente org\u00e1nico.<\/p>\n

Y no son los \u00fanicos que han dado con una soluci\u00f3n de este tipo. En la Universidad Cornell, de Nueva York, han descubierto una fibra enriquecida con una mol\u00e9cula proveniente de la degradaci\u00f3n de la celulosa, similar al carb\u00f3n activo, que absorbe las part\u00edculas perjudiciales presentes en el agua de la misma manera.<\/p>\n

Se trata de m\u00e9todos m\u00e1s sencillos y eficientes que los usados en la actualidad.<\/p>\n","protected":false},"excerpt":{"rendered":"
