Abstract

The invention discloses a method for determining the contents of monomethylamine and monoethylamine in a side-stream smoke gas of a cigarette through ion chromatography. The method includes following steps: capturing the monomethylamine and the monoethylamine, treating a smoke gas sample of a cigarette, preparing a stock solution and a standard operation solution, and respectively performing ion chromatographic analysis to supernatant liquids. By means of the method, accurate determination of the monomethylamine and the monoethylamine can be achieved and defects that a derivatization-gas chromatographic method, which is used for determining the monomethylamine and the monoethylamine in a main-stream smoke gas of the cigarette in the prior art, is complex in operations, needs a long time and much labor intensity and is difficult in accurate quantitation are overcome. The method is simple in pre-treatment, is accurate, is high in sensitivity and is good in repeatability. According to distributing situations of the monomethylamine and the monoethylamine in a gas phase and a granular phase in the side-stream smoke gas, the gas phase and the granular phase are respectively treated and detected individually so that the method is more reasonable theoretically and the distributing situations of the the monomethylamine and the monoethylamine in the gas phase and the granular phase are convenient to master.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing, and in particular relates to the determination of organic amines in cigarette sidestream smoke. Background technique [0002] During the burning process of tobacco, the thermal degradation of nicotine or other alkaloids may generate monomethylamine and monoethylamine. Monomethylamine and monoethylamine have a strong stench and are harmful to the skin, eyes, upper respiratory tract and lungs. Strong stimulating and corrosive effects. When poisoned, the central nervous system is damaged, which can lead to bronchitis, bronchitis, pneumonia, and even pulmonary edema. my country stipulates that the allowable concentration of monomethylamine in the air is 5mg / m 3 . The presence of monomethylamine and monoethylamine in cigarette smoke not only has a great impact on the taste of cigarettes, but also has a negative impact on the surrounding environment in sidestream smoke.
