Abstract

The invention discloses a method for determining content of potassium, sodium, calcium and magnesium in cigarette paper simultaneously, which includes the following steps: cutting 100+ / -0.1 mg of a cigarette paper sample, using 100mL of 0.02mol / L hydrochloric acid as an extracting agent, ultrasonic-extracting for 18-22min to obtain extract liquor, selecting 5.0mL of the extract liquor to a 25mL volumetric flask, bringing to the volume with 0.02mol / L hydrochloric acid to obtain diluent, and filtering the diluent through a 0.45 mu m filtering film to obtain sample liquid to be detected; selecting sodium chloride, potassium chloride, hexahydrate magnesium chloride and anhydrous calcium chloride, using pure water as solvent, preparing mixed standard solution through gradual diluting, and adding 0.02mol / L hydrochloric acid to prepare series standard working solution; detecting and analyzing the series working solution and the sample liquid to be detected respectively through an ion chromatographic instrument; and drawing a standard curve and calculating results. The method is fast and simple to operate, high in sensitivity, low in detection limit, good in recovery rate, and suitable for batch analyzing of important inorganic elements in the cigarette paper.

Description

technical field [0001] The invention relates to a method for measuring potassium, sodium, calcium and magnesium contents in cigarette paper, in particular to a method for simultaneously measuring potassium, sodium, calcium and magnesium contents in cigarette paper. Background technique [0002] Cigarette paper is the main auxiliary material of cigarettes, which has an important impact on the overall physical properties of cigarettes and the smoke components of cigarettes. In particular, the contents of potassium, sodium, calcium and magnesium in cigarette paper are important parameters for evaluating cigarette paper, which directly affect the appearance quality and combustibility of cigarette paper. Adding light calcium carbonate to cigarette paper can not only improve the appearance and feel of the paper, but also improve air permeability and adjust the burning rate of cigarettes. Studies have found that magnesium salts can reduce the emission of harmful substances in smok...
