AKAGANEITE

Abstract: In this study it was aimed to introduce akaganeite, which is a recently produced alternative adsorbent obtained from natural materials. Its structure, properties and use in environmental works are mentioned. Akaganeite is an iron (Fe) based adsorbent found in mine ores, oceans, groundwater, hot springs, brine water bodies, acid soils and in some other natural bodies containing chloride. Although its cost is high for the time being, it is produced at temperatures much lower than activated carbon, so consuming much less energy, and it has high adsorption capacity. The physical and chemical properties of akaganeite change with its particle size, shape and morphology. Smaller particle size results in higher adsorption capacity. Heavy metals, phosphate, arsenic, uranium, surfactants are among the pollutants that can be removed from water by adsorption onto akaganeite. It can also be used in the modification of red mud used in bromine removal. It has not any adverse effects onto human and the environment. By these properties akaganeite is an environmentally important treatment material that is becoming common.
