Claim Text:
1. A multiple separation filter comprising a microfiltration membrane, an active carbon-based filter and a ceramic filter stacked in order, wherein the active carbon-based filter is obtained by mixing 60 parts by weight of active carbon with 20-40 parts by weight of zeolite powder, treating the mixture with plasma gas of 60,000° C. to 70,000° C., and then quenching the mixture to −200° C. to −273° C. under vacuum; and the ceramic filter is obtained by heating magnesium by plasma gas of 60,000° C. to 70,000° C., and quenching the magnesium to −200° C. to −273° C. under vacuum.
