使用气体溶胶以及离心旋转两种方法将吸附剂包覆于红外透明薄膜的表面,在光谱分析中起到预富集水相中有机污染物的作用。考察了包括聚四氟乙烯(PTFE),ParafilmTM,聚乙烯(PE),聚丙烯(ProleneTM),聚酯(MylarTM)在内的红外透光薄膜作为红外分析中的载体对有机物进行分析表征的能力。光谱分析数据证明,这些薄膜具有被用作吸附剂的载体的潜力,它们可以使水相中的有机污染物可以沉积在薄膜包覆层。通过气体溶胶以及离心旋转两种方式,聚有机硅被成功地涂在高分子薄膜的表面,对水相中的苯含量可以进行μL/L级别的检测。
Adsorbents are coated on the surface of the infrared transparent film using gas sol and centrifugal spin-on methods, which play the role of preconcentration of organic pollutants in the aqueous phase in spectroscopic analysis. The ability of infrared light-transmissive thin films, including PTFE, ParafilmTM, PE, ProleneTM, and MylarTM, to characterize and characterize organic compounds as carriers in IR analysis was investigated . Spectral analysis data demonstrate the potential of these films as supports for use as adsorbents that allow organic contaminants in the aqueous phase to deposit on the film coating. Through the gas sol and centrifugal rotation of two ways, poly silicone is successfully coated on the surface of the polymer film, the benzene content of the aqueous phase can be μL / L level detection.
