果がが持続することになる。[Function] In the present invention, porous calcium silicate powder is used as a carrier for hydrogen peroxide, so hydrogen peroxide is absorbed into the voids of the powder. When the granular material that has absorbed hydrogen peroxide is put into water contaminated by red tide, etc., hydrogen peroxide is gradually released and some of it reacts with plankton and floating dust in the water, especially metal oxides. active oxygen is generated, and the generated oxygen is attached to and detached from the carrier, causing the carrier to rise and fall up and down, thereby improving the dispersion of hydrogen peroxide. In addition, a part of the iron oxide acts to generate OH radicals through the Fenton reaction with iron ions in the powder and to strengthen the oxidizing power. As a result, plankton and the like can be efficiently exterminated. Furthermore, since the iron ions are gradually eluted during this process, the generation of OH radicals continues even in water. As a result, the effect of exterminating plankton etc. will continue.

For example, a porous calcium silicate hydrate containing 0.5 wt% or more of iron as a trace component is prepared by carrying hydrogen peroxide thereon, and then using the porous calcium silicate hydrate, which is contaminated with blue-green algae. It is preferable to adjust the particle size or bulk density of the carrier to pB so that the carrier floats and sinks when placed in water. Further, the carrier of the present invention may be any carrier as long as it has calcium silicate hydrate as its main component and contains 0.5 wt % or more of iron as a trace component. Further, the trace amount of iron may be derived from a siliceous raw material and/or a calcareous raw material.
