Abstract

Currently, harmful green-tide is seriously occurred by water temperature rising by climate change and inflow of excessive nutritive salts in river. To remove these harmful green-tide, red-soil and clay are using in river. However, it is induced to high cost, damage of forestland, and destruction of ecosystem. In addition, only red-soil and clay are sunken to harmful green-tide, which is growth in bottom of river. It is cause of secondary pollution. To solve these problem, we prepared to red-soil/clay-mixed chitosan. In this study, characterization of chitosan was analyzed by 1H-NMR and GPC-MALLS. Also, to confirm optimal concentration of flocculation, red-soil or clay of various concentration with chitosan of fixed concentration (5 mg/L) was treated in harmful green-tide. Moreover, its algicidal effect was analyzed by UV-vis spectrometer and, growth and chlorophyll a of harmful green-tide were decreased by red-soil/clay-mixed chitosan. Theses results suggest that red-soil/clay-mixed chitosan can be inhibit against harmful green-tide.
