Geopolymer-supported Hybrid Zeolite-hydrotalcite(LDH) Composite And Method for Manufacturing the Same

摘要

The present invention is not a method of adding zeolite, but a mixture of alkali activator and magnesium oxide (MgO) in industrial by-products such as fly ash and fine slag powder to simultaneously generate zeolite and LDH (Hydrotalcite) to adsorb cations and anions in large quantities. A bulk type heavy metal adsorption type geopolymeric hybrid zeolite-LDH composite capable of manufacturing and a method for manufacturing the same, wherein the geopolymeric hybrid zeolite-LDH composite according to the present invention is a binder made by mixing slag and fly ash at a certain ratio. ; And a magnesium oxide (MgO) powder mixed with the binder and an alkali activator; and a mixture of the binder and the magnesium oxide powder and an alkali activator is heated to a certain temperature range to perform a hydrothermal synthesis reaction, and then in water or It is made by curing in air.
