Removing Non-Biodegradable Toxic Ions via Bio-Oxidation Analysis in Anzali Lagoon: A Usage of Seaweed in Biodiversity

Abstract

Seaweed has been considered a treatment with the possibility of saving the environment in Anzali Lagoon in Iran due to its eco-potential, accessibility, and anti-toxic metal ion. Mostly, transition metals are toxic to human organs. Due to these problems and concerns, this study exhibits suitable adsorption materials for several native materials. Using the seaweeds of Anzali Lagoon in Iran for treatment has shown prominent results compared with other materials. The adsorption of transition metals by dead seaweed biomass offers a comparative advantage over other natural adsorption materials. This work describes the situation of heavy metals on the environment and why dead seaweed biomass is considered for remediation, among other materials. This work provides general ways to remove dissolved metals and toxic ions from Anzali Lagoon. Each of the various stages of operations of this lagoon will be discussed with their role in the metals removal process. The described treatment is general for metals and ion oxides removal. Some variations will exist among different systems. In layman's terms, these methods are intended to provide a suitable understanding of the precipitation process for toxic water treatment application. This investigation also provides a general method on how to remove dissolved metals (third and fourth-row elements of Mendeleyev tables) from toxic waters for discharge into sanitary systems.
