OXYGEN RELEASING ALGINATE BEADS COMPRISING METAL OXIDE AND THE METHOD OF PURIFICATION OF INFESTED SOIL OR POLLUTING SUBSTANCE OF GROUND WATER USING THE SAME

摘要

The present invention relates to an oxygen releasing alginate bead comprising a metal oxide and a method for purifying a soil or underground water pollutant using the same and more particularly, to an oxygen releasing alginate bead comprising a metal oxide, which is made to keep a pH between 5 and 7 and to generate oxygen by using a cross-linking agent for generating trivalent cations instead of calcium chloride in an existing alginate bead synthesis method using the reaction of an alginate solution and calcium chloride, and adding calcium peroxide, which is a metal peroxide, as an oxygen generating agent so as to produce oxygen releasing alginate beads (ORABs) for purifying pollutant organic chemical compounds such as BTEX and TPH in soil or underground water; and a method for purifying a soil or underground water pollutant using the same. The oxygen releasing alginate bead according to the present invention enhances the natural on-site biodegradation of microorganisms by consistently supplying oxygen to the microorganisms and keeping a proper pH and can be applied efficiently to the treatment of pollutants such as BTEX and TPH existing in soil and underground water.
