Description
본 발명은 항균기능을 갖는 금속처리-활성탄 및 그 제조방법에 관한 것이다. 보다 상세하게는 본 발명은 탄소의 활성화를 촉매하여 높은 비표면적을 가지면서도 활성화를 촉매하는 금속 또는 금속전구체에 의하여 항균기능을 갖는 금속처리-활성탄 및 그 제조방법에 관한 것이다.The present invention relates to a metal-treated activated carbon having an antibacterial function and a method of manufacturing the same. More specifically, the present invention relates to a metal-treated activated carbon having an antibacterial function by a metal or a metal precursor which catalyzes the activation of carbon and has a high specific surface area and catalyzes the activation, and a method of manufacturing the same.
유기물이나 무기물과 같은 오염물질을 제거하기 위하여 활성탄을 넓은 범위에 걸쳐서 사용하여 왔다. 활성탄은 넓은 표면적, 특징적인 기공 크기, 기공의 형상, 이들의 분포, 고흡착용량, 표면의 화학적인 특성 등의 여러 특성들을 가지기 때문에 흡착성 증대에 영향을 주는 것으로 밝혀졌다. 또한 이들 특성들을 이용하여 독특하고 다양한 흡착제로서 사용되어 왔으며, 여기에 화학적, 물리적 특성을 부가하여 흡착과정에 이용하여 왔다.Activated carbon has been used over a wide range to remove contaminants such as organics and inorganics. Activated carbon has been found to affect adsorption because it has various properties such as large surface area, characteristic pore size, pore shape, their distribution, high adsorption capacity, and surface chemical properties. In addition, these properties have been used as unique and diverse adsorbents, and chemical and physical properties have been added to the adsorption process.
최근에 활성탄 및 활성탄소섬유의 높은 흡착특성을 이용하여 금속이온 또는 금속원자를 흡착시켜서 이들의 특성을 배가시키는 방법이 활발히 연구되고 있다.Recently, a method of doubling these properties by adsorbing metal ions or metal atoms using high adsorption properties of activated carbon and activated carbon fibers has been actively studied.
이들 중 하나가 탄소 표면에 존재하는 기능기에 용액 상에서 금속전구체이온(Metal precursor ion) 또는 금속원자를 흡착시키는 것이다. 이러한 활성탄의 특성을 이용하여 식수 또는 오염수에 존재하는 높은 농도의 중금속의 농도를 저하시키는 연구가 계속되어 왔다. 이들 중금속이온은 국민건강과 다른 생태계에 대한 유해효과로 인하여 수중의 이들 중금속이온의 제거는 중요한 문제로 대두되고 있다.One of these is to adsorb metal precursor ions or metal atoms on a solution to a functional group present on the carbon surface. Research on reducing the concentration of heavy metals present in drinking water or contaminated water by using the characteristics of such activated carbon has been continued. The removal of these heavy metal ions in water is an important issue due to the harmful effects on the public health and other ecosystems.
활성탄 및 활성탄소섬유의 또 하나의 특성 중 세균이나 박테리아의 친화성을 가진다는 것이다. 따라서 물이나 공기의 정화작용도 중요하지만 병원성 세균이나 박테리아의 오염을 부수적으로 예방하여야만 한다.Another characteristic of activated carbon and activated carbon fibers is their affinity for bacteria or bacteria. Therefore, the purification of water or air is important, but it must be concomitantly prevented from contaminating pathogenic bacteria or bacteria.
한편, 종래의 항균기능을 갖는 활성탄은 우선, 통상적인 방법에 따라 가열에 의한 탄화과정과 탄화된 분말을 수증기처리하는 활성화과정을 거쳐 비표면적이 높은 활성탄을 제조한 후, 수득된 활성탄을 질산은(AgNO3)와 같은 금속전구체의 용액에 침적시키고, 20 내지 30분간 교반하여 기포를 제거한 후, 용액으로부터 활성탄분말을 분리하여 가열, 건조시켜 금속을 담지시켰었다. 이러한 종래의 방법에 의하면 금속전구체로부터 금속이온 또는 금속원자가 활성탄의 표면에 부착되어 이들 금속의 작용으로 항균기능을 갖게 된다. 그러나, 이러한 종래의 방법에 의하여 금속처리된 활성탄은 금속전구체용액에 이미 활성화되어 기공의 형성이 완료된 활성탄을 침적시켜 처리하기 때문에 금속이온 또는 금속원자가 활성탄의 기공일부를 폐색시키는 등의 문제점을 보이고 있으며, 또한 제조공정이 복잡하여 생산성이 저하되는 문제점이 있는 것으로 나타났다.On the other hand, the activated carbon having a conventional antimicrobial function, first through the carbonization process by heating and the activation process for steam treatment of the carbonized powder according to a conventional method to produce activated carbon having a high specific surface area, and then obtained activated carbon is silver nitrate ( The solution was deposited on a solution of a metal precursor such as AgNO 3 ), stirred for 20 to 30 minutes to remove bubbles, and then activated carbon powder was separated from the solution, heated and dried to carry a metal. According to this conventional method, metal ions or metal atoms are attached to the surface of the activated carbon from the metal precursor to have an antibacterial function by the action of these metals. However, since the activated carbon treated by the conventional method deposits and treats activated carbon which is already activated in the metal precursor solution and completes the formation of pores, metal ions or metal atoms block some of the pores of the activated carbon. In addition, the manufacturing process is complicated, there is a problem that the productivity is lowered.
대한민국 특허공고 89-2100 호에는 상기한 바와 같은 함침법에 의하여 은 또는 구리를 사용한 살균용 은 흡착물 및 그의 제조방법에 대하여 기술하고 있으며, 이미 제조된 활성탄을 사용하여 거기에 산화-과산화-산화의 다단계의 공정을 거치는 것이며, 또한 환원공정을 요구하는 것으로서, 함침에 의하여 활성탄의 기공이 폐색되는 문제점이 있으며, 제조공정이 복잡하여 생산성이 저하되는 문제점이 있었다.Korean Patent Publication No. 89-2100 discloses a sterilized silver adsorbate using silver or copper and a method for producing the same by impregnation as described above. As a multi-step process, and also requires a reduction process, there is a problem that the pores of the activated carbon by the impregnation has a problem, the manufacturing process is complicated, there is a problem that the productivity is lowered.
