AQUATIC ENVIRONMENT RESTORATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a material, when a silicic acid having high availability for diatoms is eluted as a nutrient salt for the diatoms, capable of efficiently supplying an ocean with the silicic acid in a use of an inorganic oxide material of a silicic system such as a slag for a hydrosphere.SOLUTION: An aquatic environment restoration material causes multiple silicic acids in a chemical state, which is useful for the diatoms, to elute into the hydrosphere by carbonating the surface of the inorganic oxide material of the silicic system such as a slag or making it coexist with carbonate.
