Liu Zechun et al. (Simultaneous determination of phthalates in cigarette tipping paper and wrapping paper by isopropanol extraction-gas chromatography, Analytical Instruments, 2010, 2:30-35) introduced the weighing of 0.25g sample to Anethole is an internal standard, adopts isopropanol ultrasonic extraction, and gas chromatography (GC-FID) measures the method for 14 kinds of phthalates in cigarette tipping paper and wrapping paper, the shortcoming that this method exists is that there is no The sample is pretreated by shredding, and the extraction efficiency of PAEs in composite printing type lining paper and cigarette rod and box wrapping paper samples is low
There are no other literature reports on the detection of phthalates in printed packaging paper

Embodiment 1

[0034] The method for determining the content of phthalates in a cigarette tipping paper adopts the internal standard method and includes the following steps:

[0035] (1) Preparation of internal standard solution

[0036] Take internal standard benzyl benzoate, be mixed with benzyl benzoate isopropanol solution, the concentration of benzyl benzoate in benzyl benzoate isopropanol solution is 20mg / mL, this benzyl benzoate isopropanol solution is the internal standard solution;

[0037] (2) Preparation of sample solution

[0038] According to the provisions of YC 171-2008, cut a tipping paper for cigarettes, that is, accurately cut a sample of tipping paper for cigarettes with a length of 200mm and a width of 40mm (should include a single side), and the mass is about 0.3g. The good cigarette tipping paper is weighed on a balance, and then the cut cigarette tipping paper is cut into pieces not larger than 0.5cm×0.5cm, and the pieces are placed in a 50mL Erlenmeyer flask with a ...

Embodiment 2

[0052] The method for determining the content of phthalates in the wrapping paper of soft-pack cigarettes adopts the internal standard method and includes the following steps:

[0053] (1) Preparation of internal standard solution

[0054] Take internal standard benzyl benzoate, be mixed with the benzyl benzoate isopropanol solution that concentration is 20mg / mL;

[0055] (2) Preparation of sample solution

[0056] According to the regulations of YC / T 207-2006, cut a piece of cigarette soft box wrapping paper of a certain brand, and the cutting area is 15.5cm×10.0cm, put the cut cigarette soft box wrapping paper on a balance and weigh it, and then Cut into pieces not larger than 0.5cm×0.5cm, put the pieces in a 50ml corked Erlenmeyer flask, add 20mL water accurately into the 50ml corked Erlenmeyer flask, soak for 30 minutes, and then pour it into the 50ml corked Erlenmeyer flask Accurately add 20mL of isopropanol and 50μL of internal standard solution, then ultrasonically ex...

Embodiment 3

[0062] The method for determining the content of phthalates in inner lining paper for cigarettes adopts the internal standard method and includes the following steps:

[0063] (1) Preparation of internal standard solution

[0064] Take internal standard benzyl benzoate, be mixed with the benzyl benzoate isopropanol solution that concentration is 20mg / mL;

[0065] (2) Preparation of sample solution

[0066] According to the regulations of YC 264-2008, cut the inner lining paper of a certain brand of cigarettes, and the cutting area is 167cm 2 , put the cut cigarette soft box wrapping paper on a balance and weigh it, then cut it into pieces not larger than 0.5cm×0.5cm, put the pieces in a 50mL conical flask with a stopper, and pour it into the 50ml conical flask with a stopper Accurately add 20mL of water, soak for 30 minutes, then accurately add 20mL isopropanol and 50μL internal standard solution to the 50ml Erlenmeyer flask with stopper, then ultrasonically extract for 30 m...

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 ...
