Problems solved by technology
Tributyl phosphate is also a commonly used plasticizer, which mainly appeared in daily necessities such as toothpaste at first. Modern research shows that it has a strong stimulating effect on the skin and respiratory tract, and has a systemic toxic effect.
[0005] At present, there is no relevant method recommended for the determination of plasticizers in popping beads for cigarettes. The detection of phthalate and tributyl phosphate plasticizers in popping beads for cigarettes will be relevant to the industry-related supervision and inspection work. provide the necessary basis

Embodiment
[0042] Embodiment: Determination of the plasticizer in the standard sample of popping beads for cigarettes.
[0043] 1) Sample pretreatment
[0044] Weigh 0.2-0.3g of pop-bead samples into a 25 mL Erlenmeyer flask with a stopper, accurate to 0.0001 g, add a number of ceramic homogeneous particles, and add diethyl phthalate (DEP ) and di(2-ethyl)hexyl phthalate (DEHP) single standard solution (solvent is isopropanol), 5-10 mL isopropanol and 100 µL internal standard solution (deuterated-phthalate di butyl ester concentration of 0.1 mg / mL isopropanol solution), using a vortex shaker, vortex shaking at 2000 rpm for 5 min, after the beads are broken, take an appropriate amount of supernatant, and pass through a 0.22 μm nylon filter membrane.
[0045] 2) Blank experiment
[0046] Repeat step (1) without adding sample.
[0047] 3) Instrument analysis
[0048] It was measured by GC-MS, and the measurement conditions were as follows.
[0049] Gas chromatography conditions:
[0...

Abstract
The invention relates to a method for determining phthalic acid esters and tributyl phosphate plasticizers in exploding beads for cigarette. The method is characterized by comprising the following steps: mixing protons of the exploding beads and inert ceramics under the existence of a solvent; adopting an external force shocking method (vortex) for breaking the exploding beads; and adopting a micro-membrane for filtering the mixed solution appearing after the breaking of the exploding beads, and then adopting gas chromatography-mass spectrum (GC-MS) combination for realizing the high throughput test for different plasticizers. According to the method, the breaking of the exploding beads and the extraction of the target objects are completed in one step, and meanwhile, the determination for the phthalic acid esters and the tributyl phosphate plasticizers is realized. The method has the advantages of higher determining flux, high recovery rate and high accuracy.
Description
technical field [0001] The invention belongs to the field of physical and chemical analysis of harmful components of cigarette additives, in particular to a method suitable for determining phthalate and tributyl phosphate plasticizers in cigarette popping beads. Background technique [0002] Popping beads for cigarettes are small spherical rubber beads with a liquid with a high concentration of fragrance (usually mint or other related fragrances) inside. Popping beads are generally placed in the filter rod of cigarettes. When smokers smoke cigarettes, they crush the popping beads with their hands, and the flavor liquid in them flows out, making the smoke have a cold and moist sense of harmony, neutralizing to a certain extent It harmonizes the roughness and irritation of the smoke, and improves the taste of the smoke. [0003] Once the pop-pear cigarette came out, it attracted the attention of many cigarette manufacturers. By the end of 2015, there were nearly 20 types of p...
