PURPOSE: A method for controlling harmful algae using water soluble organic clay is provided to prevent effect to other marine ecosystems and to selectively prevent the harmful algae. CONSTITUTION: A water soluble organic clay controls harmful algae. The water soluble organic clay is metal ionic phylloxilicate having attached functional group selected from amino propyl, mercaptopropyl, methyl, phenyl, methacryloxy propyl, and glycyldeoxypropyl group. The functional group is amino propyl. A method for preparing the water soluble organic clay comprises: a step of dissolving magnesium chloride hexahydrite in ethanol; a step of adding 2-aminopropyl triethoxy silane(APTES) to the magnesium chloride hexahydrite to form a white float; a step of stirring the solution having the white float; a step of centrifuging the solution to separate into precipitate and supernatant; a step of suspending the precipitate in ethanol and centrifuging 2-5 times; and a step of dissolving water soluble organic clay in distilled water. |
