Role of ion track filters in environmental surveillance

Ion track filters (ITFs) are produced by physiochemical treatments to thin films of polymers and mica irradiated by heavy ions. These ITFs have many applications in the fields of science and technology. In the present investigation, the developed ITFs from polycarbonate films have been used to filter bacteria of various types in water. It is observed that the electric conduction through these filters depends upon the concentration of contaminants and pore diameter of filters. Filtration experiments were carried out using both single and multipore filters. Other applications related to environment surveillance have also been reported.
