本研究的目的是利用對含苯化合物及重金屬具有良好吸附性的去氧核醣核酸(DNA)壓吸(Padding)於聚酯纖維布(PET)上，製備成具良好吸附性之空氣過濾材。並於D65標準光源及SEM觀察樣本吸附DNA前後及各比例添加量之表面差異性，再以紫外光譜分析法將苯環及尼古丁以Beer–Lambert law做定量測試。探討樣本的DNA添加量對於苯酚及甲苯的吸附性能之提升，並採用FTIR分析法檢定空氣過濾材於香菸吸附前、後之特徵官能基。 經實驗結果得知，DNA確實能以壓吸法良好的與PET纖維布結合，並由紫外吸收光譜分析法測定出樣本對於含苯化合物及尼古丁之吸附性會隨DNA添加量的增加而提升，也於FTIR分析法中得知樣本能吸附含苯化合物。由此研究結果可知DNA能有效提升空氣過濾材對含苯化合物之吸附性。
The aim of this study was to prepare a well-adsorbed air filter using a deoxynucleoside acid (DNA), which is a good adsorbent for benzene-containing compounds and heavy metals at polyester(PET) fiber cloth.
The different surface of the samples was observed by D65 light source and SEM. The benzene ring and nicotine were analyzed by Ultraviolet–visible spectroscopy then quantified by Beer-Lambert's law.The increase of the adsorption capacity of phenol and toluene was discussed,The increase of the adsorption capacity of phenol and toluene was discussed, The functional groups were analyzed by FTIR analysis before and after the sample adsorption. Experiments show the DNA is indeed able to padding a good combination with PET fiber cloth,And by UV absorption spectroscopy to determine the sample for benzene compounds and nicotine adsorption will increase with the increase in DNA,Also in the FTIR analysis that the sample can adsorb benzene-containing compounds. The results show that DNA can effectively improve the air filter material absorption of benzene compounds.
