Due to advancement of industrial development, heavy metal ions in waste water are daily flowing into ground surface and water resources. Cases of serious side effects have been reported since they are accumulated in the human body along the food chain. Because of effectiveness of adsorption process, numerous adsorbents have been proposed for efficient removal of heavy metal ions or organic pollutants in waste water. However, previously reported adsorbents and adsorption process are not suitable for small scale enterprise and individual user. Development of a portable heavy metal ion remover which can be used even by untrained user is highly demanded. Polymer brushes possess advantages of numerous reaction sites and pH-responsive behaviors for control of adsorption/desorption. Thus, highly porous sponge composites decorated with polymer brushes was developed for fast and efficient removal of heavy metal ions or organic pollutants in waste water or drinkable water. |
