||Recently, the shutting down of Kori 1 has become a big issue, which is one of the old nuclear power plants in Korea. Because radioactive waste is very harmful to human health and environment, much attention has been paid to removal of radioactive materials. Decontamination liquid wastes generated during the decontamination process contain many surfactants used for removal of radioactive nuclides. These surfactants have a lot of difficulties in the treatment of decontamination waste liquid. Sodium dodecylbenzenesulfonate (SDBS) is used as an anionic surfactant in various fields because of its low price. These surfactants are also used to remove radioactive nuclides. It is possible to produce porous nanofibers by electrospinning, which will be used to adsorb SDBS because the porous nanofibers have large surface area.
