Abstract

The invention provides a method for separating and measuring arsenic elements with different forms in main stream smoke of cigarettes. According to the method, AB-8 resin is adopted for separating, and the content of the arsenic elements with different forms in the main stream smoke of the cigarettes can be measured by an inductively coupled plasma mass spectrometry method, wherein the arsenic elements with different forms are inorganic arsenic and organic arsenic. The method for separating and measuring the arsenic elements with different forms in the main stream smoke of the cigarettes is good in reproducibility and recovery rate, is beneficial to the effective quantitative measurement control of related technical personnel of the tobacco industry for the contents of the arsenic elements with different forms in the main stream smoke of the cigarettes, and provides a powerful technical support for comprehensively and objectively evaluating the harmfulness of the arsenic elements in the main stream smoke of the cigarettes in the tobacco industry.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and in particular relates to a method for separating and measuring arsenic elements in different forms in cigarette mainstream smoke. Background technique [0002] As a heavy metal element, arsenic has received extensive attention and research in recent years because of its great harm to humans and the environment. Arsenic in cigarette smoke is one source of chromium in the environment and one of the harmful components listed in the Hoffmann list within the tobacco industry. When smoking cigarettes, arsenic will be inhaled into the bronchi, which will cause harm to the lungs, liver, kidneys and other organs of the human body. According to toxicology, different forms of arsenic have different toxicity, inorganic arsenic (As 2 o 3 , AsO 3 3- , AsO 4 3- ) is highly toxic, organic arsenic is less toxic, and trivalent arsenic in inorganic arsenic is more toxic than penta...
