Abstract

The invention relates to a preparation method and application of benzene series visual detection test paper, and mainly solves the problems of poor selectivity, complex operation and high cost in theprior art. The invention adopts the technical scheme that the preparation method of the benzene series visual detection test paper is adopted; the test paper is prepared by a test paper matrix material supported with a platinum II complex PtII through impregnation (TMSC-triple bond-CPhenC-tripe bond-CTMS) (C-tripe bond-CC6H4F-2)2, and the test paper matrix material is filter paper without a fluorescent whitening agent. The technical scheme well solves the problems, and can be used in preparation of benzene series visual detection test paper.

Description

technical field [0001] The invention relates to a preparation method and application of a benzene series visual detection test paper, belonging to the field of preparation and application of sensor materials. Background technique [0002] Benzene series are widely used in industrial production and people's daily life, but due to the strong volatility of most benzene series (such as benzene, toluene, xylene, chlorobenzene, nitrobenzene, etc.), in its production Air pollution will be caused by volatilization during storage, transportation and use. Benzene series have high photochemical reactivity in the atmosphere, and have a considerable effect on the formation of photooxidants (such as ozone and peroxyacetyl nitrate, etc.) and secondary organic aerosols in the atmosphere, destroying the ecological environment. In addition, benzene series are highly carcinogenic, and long-term inhalation of benzene series can lead to various serious diseases such as regenerative anemia, leuk...
