【摘要】：氧氣和臭氧均是大氣中常見氣體。氧氣是非極性分子,吸收特性較差,很難對(duì)其濃度進(jìn)行精確測(cè)量,因此發(fā)展簡(jiǎn)單精確的氧氣檢測(cè)技術(shù)是十分必要的。氧氣在紫外光照射下會(huì)產(chǎn)生臭氧,然而目前缺乏對(duì)氧氣紫外光催化轉(zhuǎn)化產(chǎn)生臭氧這一過程的定量描述。紫外吸收光譜檢測(cè)技術(shù)以其非接觸測(cè)量、高分辨率、高靈敏度、可實(shí)時(shí)在線監(jiān)測(cè)等特點(diǎn)被廣泛應(yīng)用于氣體測(cè)量。本文基于Beer-Lambert定律,分別開展了對(duì)氧氣、臭氧紫外吸收光譜檢測(cè)技術(shù)的探究。開展氧氣濃度檢測(cè)的紫外吸收光譜檢測(cè)技術(shù)的研究。利用氧氣在186~196nm真空紫外吸收波段,基于積分光譜法構(gòu)建了氧氣紫外吸收光譜檢測(cè)理論,并建立了實(shí)驗(yàn)系統(tǒng);確定了氧氣的光學(xué)參量,測(cè)量了氧氣光學(xué)參量的定標(biāo)曲線,并測(cè)得氧氣紫外吸收光譜檢測(cè)技術(shù)的探測(cè)限為0.3%,測(cè)量不確定度為±0.2%。開展氧氣濃度檢測(cè)的紫外二級(jí)吸收光譜檢測(cè)技術(shù)的研究。構(gòu)建了氧氣紫外二級(jí)吸收光譜檢測(cè)理論,設(shè)計(jì)實(shí)驗(yàn)成功將二級(jí)光譜從總透射光譜中提取出來;確定了氧氣的光學(xué)參量,測(cè)量了氧氣光學(xué)參量的定標(biāo)曲線,并測(cè)得氧氣紫外二級(jí)吸收光譜檢測(cè)技術(shù)的探測(cè)限為0.3%,測(cè)量不確定度為±0.3%。開展氧氣紫外光催化轉(zhuǎn)化過程及臭氧紫外吸收光譜檢測(cè)技術(shù)的探究。實(shí)驗(yàn)中確定了臭氧的光學(xué)參量,得出氧氣紫外光催化轉(zhuǎn)化過程中臭氧的產(chǎn)生速率與初始氧氣濃度成正比;測(cè)得紫外光照下氧氣光學(xué)參量變化量與臭氧光學(xué)參量變化量之間呈線性關(guān)系,并根據(jù)氧氣的光學(xué)參量定標(biāo)曲線,得出了臭氧光學(xué)參量的定標(biāo)曲線。
[Abstract]:Oxygen and ozone are common gases in the atmosphere.Oxygen is a nonpolar molecule with poor absorption characteristics, so it is difficult to measure its concentration accurately. Therefore, it is necessary to develop a simple and accurate oxygen detection technique.Oxygen can produce ozone under ultraviolet light, however, there is a lack of quantitative description of the process of ozone generation by ultraviolet photocatalytic conversion of oxygen.UV absorption spectrum detection technology is widely used in gas measurement due to its non-contact measurement, high resolution, high sensitivity, real-time on-line monitoring and so on.Based on Beer-Lambert 's law, the detection techniques of oxygen and ozone ultraviolet absorption spectra were studied.The study of ultraviolet absorption spectrometry for oxygen concentration detection was carried out.Using oxygen in the 186~196nm vacuum ultraviolet absorption band, based on the integral spectrum method, the theory of oxygen ultraviolet absorption spectrum detection is constructed, and the experimental system is established, the optical parameters of oxygen are determined, and the calibration curve of oxygen optical parameters is measured.The detection limit of oxygen ultraviolet absorption spectrometry is 0.3 and the uncertainty of measurement is 鹵0.2.To study the detection technology of oxygen concentration by UV-2-level absorption spectrum.The theory of oxygen ultraviolet secondary absorption spectrum detection was constructed, and the secondary spectrum was extracted from the total transmission spectrum successfully, the optical parameters of oxygen were determined, and the calibration curves of oxygen optical parameters were measured.The detection limit of oxygen ultraviolet second order absorption spectrometry is 0.3 and the uncertainty of measurement is 鹵0.3.The process of oxygen ultraviolet photocatalytic conversion and the detection technology of ozone ultraviolet absorption spectrum were studied.The optical parameters of ozone are determined in the experiment. It is concluded that the rate of ozone generation is proportional to the initial oxygen concentration in the process of photocatalytic conversion of oxygen.The linear relationship between the changes of oxygen optical parameters and ozone optical parameters under ultraviolet light was obtained. According to the calibration curves of optical parameters of oxygen, the calibration curves of ozone optical parameters were obtained.
