碩士<br>大葉大學<br>生物產業科技學系碩士在職專班<br>97<br>Tilapia is one of the commercially important fish species in Taiwan. Approximately 90 thousand of tons Tilapia fish scale were processed annually. This has prompted a growing research interest in the production of fish scales adsorbents from a range of residues mainly industrial or fishery by products. Tilapia fish scale was studied as a potential adsorbent for the adsorption of Reactive Red 198（R-R 198）from aqueous solution. In addition, Tilapia fish scale studies were conducted to explore zeta potential, the different dyes to removal color and adsorbanc

Abstract:
Radionuclide liquid wastes generated from nuclear facilities can affect humans and the environment, thus substantial attention for their safe management has been received worldwide. Treatment of radionuclide liquid wastes is an important step in its management. In the present work, new composite nanomaterials, graphene oxide base nanomaterial (GO) are developed for treatment purpose. Graphene oxide (GO), one of the most graphene derivatives, its unique properties, such as chemical stability, hydrophilicity, large surface area and functional groups, make them able to form strong chemical bonds
