Example Embodiment

[0033] Example 1

[0034] An internal standard method is used to determine the content of phthalates in a cigarette tipping paper, including the following steps:

[0035] (1) Prepare internal standard solution

[0036] Weigh the internal standard substance benzyl benzoate and prepare it into a benzyl benzoate isopropanol solution. The concentration of benzyl benzoate in the benzyl benzoate isopropanol solution is 20 mg / mL. The benzyl benzoate isopropanol solution It is the internal standard solution;

[0037] (2) Prepare sample solution

[0038] Cut a cigarette tipping paper according to YC 171-2008, that is, accurately cut a sample of a cigarette tipping paper with a length of 200mm and a width of 40mm (should include a single side), the mass is about 0.3g, and it will be cut The good tipping paper for cigarettes is weighed on a balance, and then the cut tipping paper for cigarettes is cut into fragments no larger than 0.5cm×0.5cm, and the fragments are placed in a 50mL triangular fl...

[0051] Example 2

[0052] The method for determining the content of phthalates in soft-box cigarette packaging paper adopts the internal standard method and includes the following steps:

[0053] (1) Prepare internal standard solution

[0054] Weigh the internal standard substance benzyl benzoate and prepare a 20mg / mL benzyl benzoate isopropanol solution;

[0055] (2) Prepare sample solution

[0056] According to YC / T 207-2006, cut a piece of cigarette soft box packaging paper of a certain brand with a cutting area of ​​15.5cm×10.0cm. Place the cut cigarette soft box packaging paper on a balance and weigh it. Cut into fragments not larger than 0.5cm×0.5cm, put the fragments in a 50ml flask with a stopper, add 20mL of water to the 50ml flask with a stopper, soak for 30 minutes, and then put it in the 50ml flask with a stopper Accurately add 20mL of isopropanol and 50μL of internal standard solution, and then ultrasonically extract for 30 minutes. After cooling to room temperature, take...

Abstract

The invention relates to the technical field of physical and chemical inspection of paper materials for cigarette, and in particular discloses a method for determining the content of phthalate in the paper material for the cigarette. The method utilizes an internal standard method and comprises the following steps of: preparing an internal standard solution, mixing a standard operation solution with a sample solution, respectively carrying out analysis detection on the mixed standard operation solution and sample solution through GC-MS (Gas Chromatography Mass Spectrometry), and obtaining the content of phthalate in the paper material for the cigarette according to the detection result. According to the method for determining the content of the phthalate in the paper material for the cigarette, disclosed by the invention, a process method of the sample and the GC-MS detection conditions are optimized, the extraction efficiency of the phthalate in the sample to be detected is remarkably improved; in addition, the method for determining the content of the phthalate in the paper material for the cigarette, disclosed by the invention, has the advantages of exactness in operation, high sensitiveness and accuracy, and good repeatability; if the detection limit is detected through three times of the ratio of signal to noise, the detection limit is 0.3mu g/g-0.6mu g/g; and the spiked recovery rate is 90.2-100.6%, and the relative standard deviation is 2.2-6.7%.

Description

technical field [0001] The invention relates to the technical field of physical and chemical inspection of additives in paper materials for cigarettes, in particular to a method for measuring the content of phthalates in paper materials for cigarettes. Background technique [0002] Phthalate esters (PAEs) refer to esterified derivatives of phthalic acid, generally referring to esters formed between phthalic acid and alcohols with 4 to 15 carbons. PAEs can increase the plasticity and fluidity during processing, increase the flexibility of products, and increase the adhesion of coatings and inks. Therefore, as plasticizers and softeners, PAEs are widely used in plastics, rubber, and leather. , Adhesives, coatings, inks and other products can also be used as raw materials for the production of cosmetics, fragrances, lubricants and defoamers. [0003] A large amount of ink printing materials are used in the cigarette production process, and adding PAEs compounds to the ink can ...
