Zusammenfassung: | The present invention relates to a method for selectively separating mineral, which includes: (a) performing primarily electrodialysis with respect to mineral seawater or seawater-treated water to obtain monovalent cation concentrated-water and divalent cation concentrated-water, respectively; (b) allowing the divalent cation concentrated water obtained in step (a) to pass through a cation exchange resin to obtain mineral concentrated water in which a divalent cation, which is contained in the divalent cation concentrated water, is substituted with a monovalent cation; and (c) secondarily performing electrodialysis with respect to the concentrated mineral water obtained in steps (c) and (b) to obtain a primary cationic mineral composition and a trace mineral composition, respectively. Various mineral compositions finally obtained in the separating method may be usefully used as various compositions such as a cosmetic composition, a food composition, and a pharmaceutical composition.
본 발명은 (a) 미네랄 해수 또는 해수 처리수를 1차 전기투석하여 1가 양이온 농축수 및 2가 양이온 농축수를 각각 수득하는 단계; (b) 상기 (a) 단계에서 수득한 2가 양이온 농축수를 양이온 교환 수지에 통과시켜, 상기 2가 양이온 농축수 내 2가 양이온이 1가 양이온으로 치환된 미네랄 농축수를 수득하는 단계; 및 (c) 상기 (b) 단계에서 수득한 미네랄 농축수를 2차 전기투석하여 1차 양이온 미네랄 조성물 및 미량 미네랄(trace mineral) 조성물을 각각 수득하는 단계를 포함하는 미네랄의 선택적인 분리방법에 관한 것으로, 상기 분리방법에 의해 최종적으로 수득된 다양한 미네랄 조성물은 화장료 조성물, 식품 조성물 및 약학적 조성물 등 다양한 조성물로 유용하게 사용할 수 있다. |
