Wastewater, pesticides, household sewage discharged from various industrial activities contain a large amount of heavy metals, and are introduced into rivers causing serious risks to the human body and ecosystem. In this study, we suggest a wastewater disposal agent that removes heavy metal ions from wastewater by surface complexation and ion exchange between heavy metal cations and carboxyl groups in porous structures. It can be used by manufacturing nanomaterials having a porous structure using alginic acid with biocompatibility characteristics. It provides an effective, economical and environmentally friendly decontamination technology for removing heavy metals from wastewater. we established conditions for an optimal structure by fabricating a porous nanostructure, confirmed whether heavy metal adsorption characteristics can be realized, and evaluated heavy metal ion adsorption removal characteristics. |
