Abstract

The invention provides a separating and measuring method for arsenic elements with different valence states in cigarette mainstream smoke. The arsenic elements with the different valence states are separated by adopting an AB-8 resin and 717-anion exchange resin, and then the contents of the arsenic elements with the different valence states in the cigarette mainstream smoke are measured by adopting inductively coupled plasma mass spectrometry, wherein the arsenic elements with the different valence states comprise trivalent arsenic and pentavalent arsenic. The separating and measuring method for the arsenic elements with the different valence states in the cigarette mainstream smoke disclosed by the invention is high in reproducibility and recovery rate, is favorable for relevant technical staff in tobacco industry to perform effective and quantitative measurement and control on the contents of the arsenic elements with the different valence states in the cigarette mainstream smoke, and provides powerful technical support for comprehensive and objective evaluation of the harmfulness of the arsenic elements in the cigarette mainstream smoke 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 valence states in mainstream smoke of cigarettes. 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 tox...
