FINE IRON MIXTURE, METHOD FOR UTILIZING FINE IRON MIXTURE, AND PROCESS FOR PRODUCING FINE IRON MIXTURE

摘要

Disclosed is a fine iron mixture which enables the satisfactory supply of iron ions into water to promote the regeneration of a seaweed bed, thereby improving a water environment. The fine iron mixture comprises fine iron, iron oxide, carbon, and an organic acid capable of binding to a dissolved bivalent iron ion to form a chelate, and can be used for the purpose of supplying iron ions into water.
