Abstract:
The present invention provides a magnesium compound-alginate complex comprising: porous alginate gel; and a magnesium compound deposited in pores of the porous alginate gel, a manufacturing method thereof and a removing method for heavy metals using the same. The present invention promotes the precipitation of heavy metals by increasing the pH of an aqueous solution, removes heavy metals through precipitation when the magnesium compound-alginate complex is used for removing pollutants, is able to remove pollutants by using the adsorption ability of the porous alginate gel and is economical and efficient by reducing treatment costs since sewage sludge and floating matters are not generated.
