Embodiment 1

[0015] The specific steps of detection are:

[0016] First use ultraviolet light to irradiate the ethanol solution polluted by hexachlorobenzene; wherein, the wavelength range of ultraviolet light is 340~380nm, and the wavelength of ultraviolet light is selected to be 360nm now, and the concentration of hexachlorobenzene in the hexachlorophenyl alcohol solution is 10 -7 M. Then use the fluorescence spectrometer to measure the fluorescence emission spectrum intensity of the hexachlorobenzene in the hexachlorophenyl alcohol solution, obtain as follows figure 1 The hexachlorobenzene content shown in the curve.

Abstract

The invention discloses a method for detecting hexachlorobenzene. The method comprises the hexachlorobenzene and particularly comprises the following completing steps of: firstly, irradiating alcohol solution polluted by the hexachlorobenzene by using ultraviolet light, then, measuring the intensity of a fluorescence emission spectrum of the hexachlorobenzene in a hexachlorobenzene alcohol solution by using a fluorescence spectrograph, and obtaining the content of the hexachlorobenzene, wherein the wavelength range of the ultraviolet light is 340-380 nm, the wavelength of the ultraviolet light is 360 nm, the concentration of the hexachlorobenzene in the hexachlorobenzene alcohol solution is 10<-14> - 10<-7> M, and the concentration of the hexachlorobenzene in the hexachlorobenzene alcohol solution is preferably to be 1*10<-9> - 8*10<-9> M. The method disclosed by the invention can quickly, sensitively and effectively detect the trace hexachlorobenzene and can be widely applied to the quick trace detection of the hexachlorobenzene in environment, medicine, food and biology samples.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method of hexachlorobenzene (HCB). Background technique [0002] Hexachlorobenzene was mainly used to control wheat smut, seed and soil disinfection. The main sources of HCB in the environment are agricultural production and chemical pollution. Hexachlorobenzene is chemically stable, photolysis, chemical decomposition and biodegradation are powerless to it, and it can persist in environmental media such as water, soil and sediment for several years or even decades or longer. Hexachlorobenzene can reach the human body through inhalation, ingestion, absorption through the skin, etc., and affect the liver and nervous system, leading to organ function damage and skin damage. It is one of the human carcinogens. Studies have shown that HCB can have toxic effects on the human reproductive system. In addition, hexachlorobenzene is also highly toxic to aquatic organisms, and bioaccumul...
