Embodiment 1

[0042] 1) Preparation of sample solution: Cut the paper material for cigarettes according to the regulations of YC171-2009 to obtain a sample with a length of 200 mm and a width of 40 mm. Place the sample on a balance and weigh it to an accuracy of 0.1mg, and cut the sample into pieces no larger than 0.5cm×0.5cm with scissors; put the pieces in a 100mL Erlenmeyer flask with a stopper, add 20mL of water accurately, soak 30min; then accurately add 20mL of ethanol, ultrasonically extract for 30min, pass through a 0.22μm organic phase filter membrane after standing to obtain a sample solution.

[0043]2) Standard solution preparation: Weigh 18 kinds of PAEs standard products and dissolve them in aqueous ethanol solution. The volume ratio of water to ethanol is 1:1-2. 5ng / ml, 10ng / ml, 20ng / ml, 50ng / ml, 100ng / ml, 200ng / ml and 500ng / ml series of single standard and mixed standard solutions.

Abstract

The invention discloses a method for determining 18 phthalic acid ester compounds in cigarette paper materials. The method comprises the steps of pretreating a cigarette paper material sample to prepare a sample solution, preparing a standard solution of 18 phthalic acid ester compounds, detecting and analyzing the sample solution and standard solution respectively by adopting liquid chromatography-tandem mass spectrum, and then quantitatively analyzing by adopting an external standard method to calculate the content of 18 phthalic acid ester compounds in the cigarette paper materials. The method has the advantages of being simple and fast to operate, simple for sample pretreatment, higher in sensitivity, high in detection speed, lower in detection limit, better in reproducibility, higher in recovery rate, stronger in anti-inference capability, more accurate in qualitativeness and the like. The determination method can cope with stricter cigarette security requirement, thus providing standardized guidance for the use of PAEs (phthalic acid esters) plasticizer in cigarette industry.

Description

technical field [0001] The invention relates to a method for determining phthalate compounds, in particular to a method for determining 18 kinds of phthalate compounds in a cigarette paper material. Background technique [0002] Plasticizers, also known as plasticizers, are polymer material additives used in industry to enhance flexibility. Phthalate esters (PAEs) as plasticizers have been widely used in the processing and manufacturing of packaging materials. In recent years, there have been many reports about the illegal addition of plasticizers in food and environmental pollution. PAEs are cumulative, long-term exposure to PAEs may cause reproductive system abnormalities, and even cause teratogenic, carcinogenic, mutagenic and physiological toxicity hazards. [0003] The detection methods of PAEs mainly include liquid chromatography (LC), gas chromatography (GC), gas chromatography-mass spectrometry (GC / MS), liquid chromatography-mass spectrometry (LC / MS), gas chromatogr...
