PURPOSE: Provided is a red tide removal material, which eliminates red tide by settling essential nutrients of various algae, and a method for preparing the red tide removal material is provided. CONSTITUTION: The red tide removal material contains 17-22 wt.% of sedimentary rock powder, 18-21 wt.% of shale powder, 33-36 wt.% of plutonic rock powder and 23-26 wt.% of strong tuff powder. The method comprises steps of (a) pulverizing sedimentary rock, shale, plutonic rock and strong tuff; (b) uniformly stirring 17-22 wt.% of sedimentary rock powder, 18-21 wt.% of shale powder, 33-36 wt.% of plutonic rock powder and 23-26 wt.% of strong tuff powder in a stirrer; (c) producing zeolite by putting an alkaline aqueous solution in the stirrer and heating while stirring the sedimentary rock powder, shale powder, plutonic rock powder and strong tuff powder; and (d) converting the zeolite into imogolite by putting an acid aqueous solution in the stirrer and heating.
