제목 Polypyrrole Multilayer-Laminated Cellulose for Large-Scale Repetitive Removal of Toxic Heavy Metal Ions
초록 In this research, we report the polypyrrole (PPy) multilayer-laminated cellulose network aiming at the cost-effective removal of aqueous heavy metal ions with high adsorption efficiency and good adsorbent recyclability. The PPy multilayer-deposited cellulose exhibited the stable adhesion between vapor-deposited PPy and underlying cellulose support even in a strongly acidic solution. Using this hybrid material, the efficient adsorption of mercury ions at a large range of pH could be performed with the maximum specific adsorption capacity of 29.51 mg/g, either in the form of thick suspended adsorbent for large-scale decontamination or thin dripper-type membrane for portable water purification. Furthermore, the PPy multilayer-laminated cotton fabric enabled the large-scale repetitive removal of mercury ions (100 ppm, 1 liter) with decent efficiency (> 91%).
