Metal-graphene hybrid material for removing arsenic adsorption and its preparation method, and adsorption removal method of arsenic ion using the same

摘要

The present invention relates to a metal-graphene hybrid material for adsorption and removal of arsenic, and in detail, for adsorption and removal of arsenic including calcium lanthanum sulfide (CaLa ₂ S ₄ ) and graphene oxide as a support The present invention relates to a metal-graphene hybrid material, a method for manufacturing the same, and a method for adsorbing and removing arsenic ions using the same. The present invention provides a metal-graphene hybrid material for adsorption and removal of arsenic, a method for producing the same, and a method for adsorbing and removing arsenic ions using the same, so that trivalent arsenic and pentavalent arsenic can be simultaneously removed, compared to conventional arsenic adsorbents. It shows excellent adsorption efficiency, can be synthesized without using a solvent, and has the effect of not generating contaminants after synthesis.
