-LDH Geopolymer-supported Hybrid Zeolite-hydrotalciteLDH Composite And Method for Manufacturing the Same

摘要

The present invention relates to a bulk-type heavy metal-adsorbing geopolymer-supported hybrid zeolite hydrotalcite (LDH) composite capable of absorbing a large amount of cations and anions, and a method for manufacturing the same by mixing industrial byproducts, such as fly ash and fine dust of slag, with an activating agent and magnesium oxide (MgO) to produce zeolite and LDH at the same time. The geopolymer-supported hybrid zeolite-LDH composite includes: a binder obtained by mixing slag with fly ash at a predetermined ratio; and magnesium oxide (MgO) powder and an alkali activating agent mixed with the binder, and is obtained by heating the mixture of the binder with magnesium oxide powder and the alkali activating agent to a predetermined temperature to carry out hydrothermal synthesis reaction, and curing the resultant product in the air or water.
