は向かない。 Conventional basic gas detection methods include gas chromatography and solution conductivity methods, for example, as ammonia gas detection methods. However, the gas chromatography method and the solution conductivity method have the following drawbacks. That is, the gas chromatography method has disadvantages in that it requires time and effort to collect the sample to be investigated, and the gas chromatograph device itself is relatively expensive. The solution conductivity method also has the disadvantage that it takes time and effort to mix the solution and the sample gas to be investigated, and the preparation of the solution, such as the production of pure water, is also troublesome.
Furthermore, this method is a quantitative spectroscopy and is not suitable for qualitative spectroscopy.

する。 It was discovered that the lanthanide diphthalocyanine complex reacts sensitively to basic gases, causing a change in color tone.The production of the lanthanide diphthalocyanine complex involves adding a lanthanide metal nitrate, chloride, etc. to a phthalocyanine solution. This is possible by adding and reacting. It is purified by known methods such as extraction and sublimation.

く変色し、後大気中で赤色のまま安定である。 The lanthanide diphthalocyanine complex 3 is retained inside the carrier 2. As a manufacturing method, for example, a chloroform solution of a lanthanide diphthalocyanine complex (a lanthanide having an atomic number of 58 to 71, such as europium, lutetium, or ytterbium is selected as the central metal) is dropped onto the carrier 2 and dried. Made. Alternatively, it may be made according to the method illustrated in FIG. That is, the spot of the lanthanide diphthalocyanine complex prepared as described above is developed with, for example, chloroform, and the developed part of the lanthanide diphthalocyanine complex is used as a basic gas detection element. The spot color of the lanthanide diphthalocyanine complex immediately after production is similar to the color of the chloroform solution, but it quickly turns red under an acidic atmosphere and remains stable as red in the atmosphere.

ておくだけでも赤色の状態にもどる。 These basic gas detection elements exhibit a red color in the atmosphere, but when exposed to basic gas, the oxidized form of the lanthanide diphthalocyanine complex is reduced, turning the color green, making it easily visible to the human eye. Can be identified. (This color change occurred more quickly in the element made according to the method explained in Figure 2.) Furthermore, even if the element had once turned green, it could be changed to red by contacting it with hydrogen chloride gas. It can be returned to its original state and used again as a basic gas detection element. Also, if a green element is left in the atmosphere, it will return to its red state.
