Description
본 발명은 수퍼 옥사이드 음이온 라디칼을 이용한 친환경적 세탁 방법에 관한 것이다.
The present invention relates to an environmentally friendly washing method using a superoxide anion radical.
종래의 산업용 세탁 공정은 (1) 예비 세탁, (2) 본 세탁, (3) 표백 및 (4) 살균(소독)의 4단계로 이루어져 있으며, 각 공정마다 10분 내지 30분의 시간이 소요된다. 또한, 분말 형태의 세제나 표백 살균제를 사용함으로써 세탁용수를 과다하게 사용하고 있으며, 표백 살균시 섭씨 80℃ 이상에서 30분 이상 세탁기를 가동함으로써 세탁기의 가동 에너지 및 스팀 에너지를 과다하게 사용하고 있다. 또한, 종래의 과산화수소를 이용한 살균 및 표백 방법은, 열을 가하여 과산화수소를 분해시키는 과정에서 발생하는 산소나 발생기 산소로 알려진 퍼하이드록실 이온을 이용하여 살균 및 표백을 하는 방식이었는데, 이러한 열분해 방법은 시간과 열이 많이 요구되기 때문에, 스팀 에너지 및 세탁기 가동 에너지를 많이 필요로 할 뿐만 아니라 세탁물의 손상을 가져오는 문제점이 있었다. 따라서, 위와 같은 다단계의 공정을 단순화시키면서도 세탁 효과는 우수한 친환경적 세탁 공정에 대한 요구가 증가하고 있다. Conventional industrial laundry processes consist of four stages: (1) preliminary washing, (2) main washing, (3) bleaching, and (4) sterilization (disinfection), and each process takes 10 to 30 minutes . In addition, washing water is used excessively by using a powdery detergent or a bleach sterilizing agent. In the case of bleaching sterilization, the washing machine is operated at a temperature of 80 ° C or more for 30 minutes or more to excessively use the movable energy and the steam energy of the washing machine. Conventional sterilization and bleaching methods using hydrogen peroxide are sterilization and bleaching methods using oxygen generated in the process of decomposing hydrogen peroxide by applying heat and perhydroxyl ion known as generator oxygen, Heat and heat are required. Therefore, steam energy and washing machine energy are required not only in a large amount but also in laundry. Accordingly, there is an increasing demand for an environmentally friendly laundry process that simplifies the above-described multi-step process and has excellent washing effect.
이와 관련하여, 대한민국 공개특허 제2006-0114104호 "광촉매를 이용한 살균 장치가 구비된 드럼 세탁기"(2006.11.6. 공개)는 광촉매인 이산화티타늄을 세탁기의 세탁조 내측에 코팅하여 살균 효과를 높일 수 있는 세탁기를 개시하고 있으며, 대한민국 공개특허 제2009-0020033호 "광촉매를 사용한 공기정화장치"(2009.02.26. 공개)는 이산화티타늄을 포함하는 석영관을 갖는 자외선 램프를 사용하여 광촉매 반응에 의해 발생하는 슈퍼옥사이드, 하이드록시 라디칼 등을 사용하여 오염물질, 악취를 제거하고 바이러스, 병원성 세균 등을 살균할 수 있으며 스스로 자체 정화 기능을 발휘하여 높은 오염물질의 농도에서도 시간의 경과에 관계없이 일정한 기능을 수행할 수 있는 공기정화장치를 개시하고 있다. 그러나 이들 발명들은 모두 자외선을 방출하는 자외선 램프가 필수적이기 때문에, 자외선이 방사되는 영역에서만 그 효과를 기대할 수 있다는 제약이 있다.In this connection, Korean Patent Laid-Open No. 2006-0114104 entitled " Drum Washing Machine Having a Sterilizing Apparatus Using Photocatalyst "(published on November 6, 2006) discloses a method of coating a titanium dioxide, which is a photocatalyst, Korean Patent Laid-Open Publication No. 2009-0020033 entitled " Air Cleaning Apparatus Using Photocatalyst "(published on Mar.22, 2009) discloses an apparatus for cleaning a photocatalyst by using a UV lamp having a quartz tube containing titanium dioxide Superoxide, Hydroxy radical, etc. can be used to remove pollutants and odors, to sterilize viruses, pathogenic bacteria, etc., and to perform its own purification function to perform certain functions regardless of the passage of time even at high concentrations of pollutants. And an air purifying device that can perform the air purifying operation. However, all of these inventions have a limitation that an ultraviolet lamp that emits ultraviolet rays is essential, so that the effect can be expected only in a region where ultraviolet rays are radiated.
이에 본 발명자들은 특수한 결정 구조를 가진 이산화티타늄을 촉매로 사용하여 자외선이 없는 조건에서도 살균 및 오염제거를 할 수 있고, 이산화티타늄 촉매를 콜로이드 상태로 세탁용수에 고르게 분산시킴으로써 10,000 배 이상의 반응 표면적을 갖도록 하여 그 효과를 극대화시킨 세탁 방법을 개발하게 되었다.
Accordingly, the present inventors have found that by using titanium dioxide having a specific crystal structure as a catalyst, it is possible to sterilize and decontaminate even in the absence of ultraviolet rays, and evenly disperse the titanium dioxide catalyst in a colloidal state in the washing water, So as to develop a washing method that maximizes the effect.

본 발명은 수퍼 옥사이드 음이온 라디칼과 수산을 이용한 친환경적 세탁 방법에 관한 것이다.The present invention relates to an environmentally friendly washing method using a superoxide anion radical and an acid.
일 양태로서, 본 발명은 과산화수소를 이산화티타늄 나노촉매와 반응 시키어 수퍼 옥사이드 음이온 라디칼로 변환시키는 반응을 이용하여 표백, 살균, 탈취 등을 한 방법으로 수행할 수 있게 하였다. 본 발명의 일실시예에 있어서, 본 발명의 세탁 방법은 과산화수소, pH 10 이상의 강알칼리성 용액 및 이산화티타늄 나노촉매제를 세탁물에 동시에 가하여 수퍼 옥사이드 라디칼을 발생시키는 단계를 포함할 수 있다.
일실시예에 있어서, 상기 과산화수소, 강알칼리성 용액 및 이산화티타늄 나노촉매제는 각각 분리되어 저장되어 있다가 세탁을 시작할 때 동시에 투여되어 원하는 수퍼 옥사이드 음이온 라디칼을 생성시킬 수 있다.
In one aspect, the present invention enables bleaching, sterilization, and deodorization using a reaction of converting hydrogen peroxide with a titanium dioxide nanocatalyst to convert it into a superoxide anion radical. In one embodiment of the present invention, the washing method of the present invention may include the step of simultaneously adding hydrogen peroxide, a strong alkaline solution having a pH of 10 or more, and a titanium dioxide nanocatalyst to the laundry to generate superoxide radicals.
In one embodiment, the hydrogen peroxide, strong alkaline solution, and titanium dioxide nanocatalyst are separately stored and then simultaneously administered at the start of washing to produce the desired superoxide anion radical.
상기 과산화수소로부터 수퍼 옥사이드가 생성되고, 이로부터 산화반응을 일으키는 라디칼들이 생성되는 원리는 다음과 같다.The principle that the superoxide is generated from the hydrogen peroxide and the radicals which cause the oxidation reaction are generated are as follows.
2 H2O2 --> 2 H2O + O2 2 H 2 O 2 - > 2 H 2 O + O 2
O2 + e(-) + TiO2 --> O2(-)⊙ (수퍼 옥사이드 음이온 라디칼)O 2 + e (-) + TiO 2 -> O 2 (-) ⊙ (Superoxide anion radical)
2 O2(-)⊙ + 2 H2O --> 2 OH⊙ + 2 OH(-) + O2 2 O 2 (-) ⊙ + 2 H 2 O -> 2 OH ⊙ + 2 OH (-) + O 2
먼저, 과산화수소는 상온의 알칼리 수용액에서 물과 산소분자로 분해되고, 이로부터 생성된 산소분자는 이산화티타늄 나노촉매에 의하여 수퍼 옥사이드 이온으로 변환된다, 이렇게 생성된 수퍼 옥사이드 라디칼은 물과 반응하여 하이드록실 라디칼을 생성할 수 있다. 이때 생성된 수퍼 옥사이드 라디칼은 밝은 오렌지 색을 가지며 그 산화환원 전위는 - 2.87 eV로 약한 환원성을 갖고 있다. 그러나, 산-염기 평형에 의하여 생성되는 짝산인 하이드로퍼옥시 라디칼(hydroperoxy radical, HO2⊙) 또는 Haber-Weiss 반응에 따라 생성되는 수산화 라디칼(hydroxyl radical, OH⊙)은 강력한 산화 반응을 일으킬 수 있다. First, hydrogen peroxide decomposes into water and oxygen molecules in an alkaline aqueous solution at room temperature, and the resulting oxygen molecules are converted to superoxide ions by the titanium dioxide nanocatalyst. The resulting superoxide radical reacts with water to form hydroxyl Radicals can be generated. The resulting superoxide radical has a bright orange color and its redox potential is - 2.87 eV and has a weak reductivity. However, hydroperoxy radicals (HO 2 ⊙) or hydroxyl radicals (OH ⊙) produced by the Haber-Weiss reaction, which are produced by acid-base equilibrium, can cause a strong oxidation reaction .
이와 같이 하이드로퍼옥시 라디칼이나 수산화 라디칼은 강력한 산화력을 갖고 있으므로, 아래 식과 같이 오염 물질이나 세균 및 악취를 유도하는 유기 화합물들을 산화시켜 탄산가스와 물로 분해시킬 수 있고, 이에 따라 별도의 세제, 살균제 또는 표백제를 사용하지 않고도 보다 적은 용수로 짧은 시간 내에 원하는 세탁효과를 가져올 수 있다. Since hydroperoxime radicals and hydroxyl radicals have a strong oxidizing power, it is possible to oxidize organic compounds inducing pollutants, bacteria and odors as follows, and decompose them into carbon dioxide gas and water. Thus, separate detergents, The desired laundry effect can be obtained within a short time with less water without using bleach.
2R (유기 오염 물질, 세균, 악취 등) + O2(-)⊙ --> ROR + CO2 + H2O
이하, 본 발명을 실시예에 의해 상세히 설명하기로 한다. 그러나 이들 실시예는 본 발명을 보다 구체적으로 설명하기 위한 것으로서, 본 발명의 범위가 이들 실시예에 한정되는 것은 아니다.
2R (organic contaminants, bacteria, bad smell, etc.) + O 2 (-) ⊙ -> ROR +
Hereinafter, the present invention will be described in detail with reference to examples. However, these examples are intended to further illustrate the present invention, and the scope of the present invention is not limited to these examples.
