氨氣檢測系統及氨氣檢測方法Ammonia detection system and ammonia detection method

本發明涉及一種氨氣檢測方法，尤其是一種透過氣體中的氨氣與甲基橙的反應呈色變化及其色相值與氨氣濃度值之間的校正，進而得到氣體中之氨氣濃度值的氨氣檢測方法。本發明另涉及一種氨氣檢測系統，尤其是透過上述氨氣檢測方法檢測氣體中之氨氣濃度值的氨氣檢測系統。The invention relates to an ammonia gas detection method, in particular to a color change through the reaction of ammonia gas and methyl orange in the gas and the correction between the hue value and the ammonia gas concentration value, and then obtain the ammonia gas concentration value in the gas Ammonia detection method. The present invention also relates to an ammonia gas detection system, in particular to an ammonia gas detection system for detecting the ammonia gas concentration value in the gas through the above ammonia gas detection method.

氨氣(ammonia gas，化學式為NH 3)及/或其衍生物為習知可用於肥料、動物飼料、藥物、染劑及界面活性劑等用途的化學物質。然而，其亦為潛在的危險物質，例如若人體接觸達一定濃度值的氨氣、並達一定接觸時間，即可能會對人體的眼睛、喉嚨及鼻子產生刺激感，甚至還可能產生致命的危險。對此，例如美國政府工業衛生會議（American Conference of Industrial Hygienists，簡稱為ACGIH）即訂定了空氣中的氨氣含量監測及接觸標準：僅得暴露於含有氨氣濃度值為25.0 ppmv的環境8小時；及僅得暴露於含有氨氣濃度值為35.0 ppmv的環境15分鐘。 Ammonia gas (chemical formula: NH 3 ) and/or its derivatives are known chemical substances that can be used in fertilizers, animal feeds, medicines, dyes, and surfactants. However, it is also a potentially dangerous substance. For example, if the human body is exposed to a certain concentration of ammonia gas for a certain period of time, it may cause irritation to the eyes, throat and nose of the human body, and may even cause fatal danger. . In this regard, for example, the American Conference of Industrial Hygienists (ACGIH) has set standards for monitoring and exposure to ammonia in the air: only exposure to environments containing ammonia at a concentration of 25.0 ppmv8 hours; and only 15 minutes of exposure to an environment containing ammonia at a concentration of 35.0 ppmv.

此外，氨氣亦可能形成揮發性有機化合物(VOCs)，進而對空氣品質產生負面影響。舉例而言，當氨氣與甲醇反應時，即可能產生甲胺、二甲胺及三甲胺等含有大量氫鍵而可與其他氣體反應形成微細粒子的化學物質，因而造成空氣中細懸浮微粒(PM2.5)的濃度上升。In addition, ammonia may also form volatile organic compounds (VOCs), which can negatively affect air quality. For example, when ammonia gas reacts with methanol, chemical substances such as methylamine, dimethylamine and trimethylamine, which contain a large number of hydrogen bonds and can react with other gases to form fine particles, may be produced, resulting in fine aerosols ( The concentration of PM2.5) rises.

以下輔以圖式，以更清楚地說明各實施例。The following diagrams are supplemented to illustrate various embodiments more clearly.

請參照圖1及圖2，圖1及圖2分別繪示根據一些實施例的氨氣檢測系統1的立體圖。在圖1及圖2中，一種氨氣檢測系統1包含樣品裝置10及呈色比對裝置12。樣品裝置10包含樣品容置槽102及樣品檢測件104。Please refer to FIG. 1 and FIG. 2 . FIG. 1 and FIG. 2 respectively illustrate perspective views of an ammonia detection system 1 according to some embodiments. In FIGS. 1 and 2 , an ammonia detection system 1 includes a sample device 10 and a color comparison device 12 . The sample device 10 includes a sample holding tank 102 and a sample detection element 104 .

樣品容置槽102適於通入氣體，其中上述氣體可包含氨氣及其他氨氣以外的氣體（例如大氣中常有的氮氣、氧氣或二氧化碳）；換句話說，該氣體中亦可不含氨氣而僅含有氨氣以外的其他氣體；在此僅示例性說明上述氣體的可能實施例而非用以限制本發明。樣品檢測件104係容置於樣品容置槽102。樣品檢測件104包含呈色部1042，且呈色部1042為任何含有甲基橙的部件，例如呈色部1042為含有甲基橙的紙基 (paper-based)、陶瓷或高分子材料，或為由甲基橙與鹽類壓成的鹽片。其中，在本文中所述的甲基橙係指甲基橙(methyl orange)之酸鹼指示劑；舉例而言，甲基橙可為溶液型態的甲基橙溶液，例如含有甲基橙之酸鹼指示劑的水溶液（下稱甲基橙水溶液）。而在本文中所述的甲基橙係指酸解離常數(acid dissociation constant，縮寫為pKa)為3.47的甲基橙，其可產生呈色變化的pH值範圍為3.1-4.4。舉例而言，以甲基橙水溶液為例，當甲基橙水溶液接觸到pH值小於3.1的環境時，甲基橙水溶液即會轉變為紅色；當甲基橙水溶液接觸到pH值大於4.4的環境時，甲基橙水溶液則會轉變為黃色；而當甲基橙水溶液接觸到pH值落在3.1-4.4之間的環境時，甲基橙水溶液則會呈現介於紅色至黃色之間的橙色，其中若環境之pH值愈接近3.1，其呈色則為愈偏紅色的紅橙色，而若環境之pH值愈接近4.4，其呈色則為愈偏黃色的黃橙色。The sample holding tank 102 is suitable for passing gas, wherein the gas may include ammonia and other gases other than ammonia (such as nitrogen, oxygen or carbon dioxide commonly found in the atmosphere); in other words, the gas may not contain ammonia Instead, it only contains other gases except ammonia; here only exemplifies the possible embodiments of the above-mentioned gases and is not intended to limit the present invention.

Wherein, the methyl orange described herein refers to the acid-base indicator of methyl orange (methyl orange); for example, methyl orange can be a solution of methyl orange solution, such as containing methyl orange Aqueous solution of acid-base indicator (hereinafter referred to as methyl orange aqueous solution). The methyl orange mentioned herein refers to methyl orange with an acid dissociation constant (abbreviated as pKa) of 3.47, and the pH range of which can produce color changes is 3.1-4.4. For example, taking the methyl orange aqueous solution as an example, when the methyl orange aqueous solution is exposed to an environment with a pH value less than 3.1, the methyl orange aqueous solution will turn red; when the methyl orange aqueous solution is exposed to an environment with a pH value greater than 4.4 , the methyl orange aqueous solution will turn yellow; and when the methyl orange aqueous solution is in contact with an environment with a pH value between 3.1-4.4, the methyl orange aqueous solution will appear orange between red and yellow. Wherein, if the pH value of the environment is closer to 3.1, the color is reddish orange, and if the pH value of the environment is closer to 4.4, the color is yellower orange.

The hue value used in this article refers to the hue in the HSL (hue-saturation-lightness, that is, hue-saturation-brightness) system and/or HSV (hue-saturation-value, that is, hue-saturation-brightness) system (H), which can be used to distinguish the names of colors with different wavelengths, and it is not easily affected by saturation, brightness or lightness to produce different interpretation results (ie hue values) for different hues. Therefore, the hue value can be obtained by detecting the color rendering image, and the color corresponding to the specific wavelength of the color rendering image can be known according to the hue value. Even, by observing the change of the hue value, you can know whether the hue and its corresponding color have changed. Therefore, by observing the change of the hue value of methyl orange, you can know whether the color of methyl orange has changed. , and then know whether there is a change in the pH value of the environment that the methyl orange as the acid-base indicator is in contact with. The color comparison device 12 then calculates the pH value and/or ammonia gas concentration value corresponding to the hue value according to the relationship between the hue value and the pH value (and/or ammonia gas concentration value) of the color rendering image . Thereby, by injecting the gas into the ammonia gas detection system of some embodiments of the present invention, it is possible to know immediately whether the gas contains ammonia gas, and to further accurately judge the ammonia gas concentration value contained in the gas. Therefore, the ammonia detection system of some embodiments of the present invention can be used to prevent the human body from being exposed to harmful or fatal ammonia gas environments (such as chicken farms or livestock farms).
