Korean Unexamined Patent Publication No. 91-14148 discloses a water purifier prepared by crushing an illite ore and mixing aluminum sulfate and calcium hydroxide, and the heavy metal ions and radioactive waste ions dissolved in water by the water purifier. Although a method for preparing an adsorption sedimentation type purifying agent for purifying wastewater by flocculation of a flocculant which adsorbs organic ions is described,

The conventional techniques have a problem that the natural illite is used by physical treatment, or a waste metal adsorbing heavy metal by simply adding a heavy metal solution into the illite and stirring it. come.

In order to solve the above problems, the present invention has been studied to improve the physical properties of the illite produced a new illite composition excellent in antibacterial and adsorption effect than the conventional illite, revealing the structure of the composition It is an object of the present invention to provide an ion exchange illite and a method for manufacturing the same that can solve environmental problems.

In order to achieve the above object, the present invention relates to an ion exchange illite having the following structural formula by exchanging metal ions in the illite and a method for producing the same.

Illite used in the present invention is a contact hydrothermally modified clay mineral whose molecular formula is (Al _1.875 Fe _0.055 Mg _0.018 ) (Al _0.55 Si _3.45 ) O ₁₀ (OH) ₂ (Na _0.0446 K _0.61 ) _n H ₂ O .

Minerals are rare in the world and are distributed in Illinois, Mississippi, Canada, Quiback, Europe, Hungary, and Yeongdong, but most of them are sedimentary minerals. It is high in grade with few impurities. It has a three-layered mineral structure. Its main components are SiO ₂ , Al ₂ O ₃ , and K ₂ O. It is a yellow-white (white, red) synthetic mineral, and is 3-25 microns at room temperature. It emits 89 ~ 92% of far-infrared rays of the wavelength, it has very strong deodorizing power (98%), emits strong groups, activates water molecules in water, secures dissolved oxygen more than three times, and has strong oxygen coagulation power. (-) 2 has charge in water, adsorbs cationic organic ions in water, its own function makes moisturizing effect large, prevents direct ultraviolet rays, high activity, and improves soil soil Sikimyeo (by oxygen or the like, far infrared rays, anions, group), emits a strong anion (dry powder form: 141ion / cc) will be.

Hereinafter, described in detail through the preferred embodiment of the present invention.
