Abstract

A method for detecting cadmium content in cigarette used tipping paper is characterized in that the method can quickly and accurately detect the cadmium content in the cigarette used tipping paper by the following steps: adopting mixed acid to carry out microwave digestion for a sample, removing the acid and fixing volume, conducting detection with a graphite furnace atomic absorption spectrophotometer, etc. The method overcomes the shortcoming of the prior art in processing the sample. Compared with the traditional electric heating plate digestion manner, the microwave digestion manner can reduce the usage of samples and strong acid, improve digestion ability, cause less loss to elements to be detected in the sample and less damage to an operator, and facilitate operation. The digestion system of compound acid is completely applicable to the special material of the cigarette used tipping paper. The acid removing process is quick and easy, and a matrix modifier is adopted to eliminateinterference. After being detected by optimal heating programs, ashing temperature and atomization temperature related to atomic absorption spectrometry, the special material of the cigarette used tipping paper is recovered with high rate, and detected with accurate result. The working efficiency and the economic benefits are significantly improved.

Description

Determination method of cadmium content in cigarette tipping paper Technical field: The invention belongs to the technical field of physical and chemical inspection of tipping paper for cigarettes, and mainly relates to the technical field of measuring trace elements of tipping paper for cigarettes, in particular to a method for directly measuring cadmium content in tipping paper for cigarettes by using a graphite furnace atomic absorption spectrometer method. Background technique: According to the requirements of my country's health law, safety and health inspections should be carried out for various products that directly contact the human oral cavity. As people pay more and more attention to smoking and health issues, the safety, sanitation and environmental protection of smoking materials are getting more and more attention from all aspects. Among them, the content of heavy metals, as one of the safety indicators, has attracted more and more attention at home and abro...
