Abstract

The invention belongs to the environment protection field, not only belonging to the treatment methods for controlling sewage disposal in the nuke industry and the radiochemistry industry but also belonging to the methods for eliminating radioactive isotopes in the nature water. The invention in particular relates to a method for preparing a series of biological composite nano-water-purifying materials which take mildews with different features as the matrices and various metallic nano materials (such as oxides and hydroxides of titanium, aluminum and iron, etc.) in different nano shapes (nano particles, nano fibers and nano tubes) as the modified materials and can effectively remove the radioactive substances in the water. The method fully utilizes the adsorption effect of the microbes on the surrounding substances to attach the nano materials on the surfaces of the microbial cells, thus obviously improving the capabilities of the nano materials in adsorption and dirt removal; therefore, the nano materials can effectively remove the radioactive substances in the water.
