AMINE FUNCTIONALIZED PUMICE-BASED ADSORBENT METHOD FOR FABRICATING THE SAME

摘要

The present invention relates to a pumice-based adsorbent and a manufacturing method of the same wherein, in the use of a mineral matter incapable of an immobilization reaction of an amine group, an amine group immobilization layer is formed in advance on a surface of a mineral matter, an amine group is immobilized to the amine group immobilization layer, thereby, a possibility to remove phosphate and heavy metals is ensured and at the same time, an excellent economical efficiency is shown. The method for manufacturing the pumice-based adsorbent fixed with an amine group of the present invention comprises the steps for: preparing an amine group immobilization layer forming solution mixed with PVA and sodium alginate; inputting a pumice powder to the amine group immobilization layer forming solution; extracting a pumice powder from amine group immobilization layer forming solution and inputting to a cross-linking solution and curing the amine group immobilization layer forming solution on a surface of pumice and forming an amine group immobilization layer on a surface of pumice; and inputting the pumice having the amine group immobilization layer to a mixed solution of APTES and anhydrous toluene to fix an amine group to the amine group immobilization layer.
