Embodiment 1

[0028] The establishment of embodiment 1 detection method

[0029] 1.2 Chromatographic working conditions

[0030] IonPac AS19 anion exchange column (4×250mm); KOH eluent; flow rate 1.5mL / min; inhibition current 149mA; column temperature 23°C; injection volume 25μL;

[0031] Table 1 gradient elution conditions

[0032]

[0033] 1.3 Preparation of standard curve

[0034] Prepare 1000 μg / mL lactate, acetate, formate, chloride ion, phosphate stock solution and 2000 μg / mL citrate stock solution respectively, then take different volumes of the stock solution into 25mL volumetric flasks, and use ultrapure water Dilute to the mark, shake well, and prepare mixed standard solutions with different concentrations. The concentration ranges of the six anions are: lactate (0-5 μg / mL), acetate (0-5 μg / mL), formate (0-5 μg / mL), chloride (0-5 μg / mL), phosphoric acid Root (0~40μg / mL), citrate (0~240μg / mL).

Embodiment 2

[0053] The mensuration of embodiment 2 actual sample

[0054] According to the method of the present invention, the content of 6 kinds of anions, lactate, acetate, formate, chloride, phosphate and citrate in 5 kinds of cigarette paper samples with different specifications were measured, and the measurement results are shown in Table 4.

[0055] The results show that the amount of adjuvants added varies greatly among cigarette paper samples of different specifications. For example, no phosphate was detected in samples 1, 2, and 3, while the content of phosphate in sample 5 reached 1.5187mg / g; In the same cigarette paper sample, the addition amount of each adjuvant is also quite different. For example, in No. 2 and No. 3 cigarette paper samples, no phosphate was detected, while the contents of citrate were 14.7841mg / g, 11.3577 mg / g.

Abstract

The invention discloses an ion chromatography detection method for six negative ions in cigarette paper.Ultrapure water is adopted as an extracting agent, IonPac AS19 negative ion exchange columns are separation columns, chromatographic conditions are optimized in a targeted mode, and the ion chromatography is adopted for achieving quantitative analysis of lactate, acetate, formate, chloridion, phosphate radicals and citrate in cigarette paper samples.A result shows that the recycling rates of the six negative ions range from 91.0% to 109.5%, and the relative standard deviation ranges from 0.82% to 6.26%.The method is accurate, simple, reliable and applicable to quantitative determination of relative components, particularly six negation ions in the cigarette paper samples.

Description

technical field [0001] The technical field of detection of reconstituted tobacco leaves of the present invention, more specifically, relates to an ion chromatography detection method of six kinds of anions in cigarette paper. Background technique [0002] Cigarette paper is one of the main auxiliary materials of cigarettes, which directly participates in combustion. Its characteristics directly affect the flammability, aroma and taste of cigarettes, and are directly related to the safety of cigarette products. The additives in cigarette paper are mainly combustion regulators, ash regulators and a small amount of flavor regulators, which play a positive role in regulating the properties of cigarette paper, such as mainstream smoke, air permeability, uniformity, burning rate, ash coating performance, etc. effect. [0003] Lactate, chloride ion and phosphate play a role in regulating the burning rate of cigarette paper in cigarette paper, and phosphate can also be used as an a...
