Problems solved by technology

Although these methods can better solve the problem of determination of various components in cigarette paper, neither atomic absorption spectroscopy nor flame photometry can realize simultaneous determination of four inorganic elements, the determination process is cumbersome, and the precision and sensitivity are relatively poor; ion chromatography Chromatographic separation time is too long, not suitable for batch testing

Description

technical field [0001] The invention relates to the technical field of inspection of auxiliary materials for cigarettes, in particular to a method for simultaneously measuring the content of potassium, sodium, calcium and magnesium in cigarette paper. Background technique [0002] The characteristics of cigarette paper directly affect the combustion performance, aroma and taste quality of cigarettes, and affect the release of harmful components in cigarette smoke. Calcium carbonate is used as a cigarette paper filler, which can affect the air permeability of cigarette paper; potassium citrate and sodium citrate are the main additives of cigarette paper, and potassium (K) and sodium (Na) are the main quality indicators for evaluating the combustion performance of cigarette paper; Magnesium (Mg) salts can reduce the release of sidestream smoke from cigarettes and reduce the impact of smoking on the environment. Therefore, rapid determination of K, Na, calcium (Ca) and Mg cont...
