1. A method of preparing an ionized calcium oxide powder, comprising steps of:
washing and drying shellfish;
pulverizing the shellfish into a powder;
subjecting the powder to a heat treatment;
subjecting the powder to an electrolysis treatment; and
subjecting the powder to an ultrasonic treatment, wherein
the heat treatment is performed under an elevated temperature condition to increase a temperature within a range of 10° C./min to 100° C./min,
the electrolysis treatment is performed under a boosted voltage condition to increase an applied voltage within a range of 100 V/min to 1,000 V/min, and performed in an environment in which carbon dioxide is removed.
