Problems solved by technology
However, surfactants have both hydrophobic and hydrophilic groups. When testing water-based rubber for tobacco with high surfactant content, the existing pre-testing methods will emulsify during the extraction process, resulting in abnormal test results. The detection result of the plasticizer in the tobacco water-based adhesive is inaccurate

Abstract
The invention discloses a detection pretreatment method and detection method of a water-based adhesive for cigarettes , the method comprises the following steps: mixing cigarette water-based adhesive,an extractant and a dispersant, and carrying out vortex oscillation for a period of time to obtain an extract liquid; adding inorganic salt into the extracting solution, oscillating for a period of time, centrifuging and taking supernatant; and filtering the supernatant to obtain a to-be-detected solution. Inorganic salt is added in the liquid-liquid extraction process, and the emulsification phenomenon caused by a surfactant is destroyed by utilizing the hydrophilicity and dissociation effect of inorganic salt ions, so that a dispersing agent and an extracting agent are well layered, and theaccuracy of a detection result is guaranteed.
Description
Technical field [0001] The present invention relates to the field of cigarette water-based glue detection, and more specifically, to a pretreatment method and detection method for cigarette water-based glue detection. Background technique [0002] Cigarette water-based glue is an indispensable material for cigarette production. The pre-treatment method for the detection of water-based gum for cigarettes is as follows: Weigh a sample of water-based gum in a triangular flask, add dispersant water and extractant, shake and extract for 30 minutes, pipette an appropriate amount of extract into a centrifuge tube, and centrifuge and take the supernatant. GC / MS analysis. [0003] In the production process of tobacco water-based glue, an appropriate amount of surfactant is usually added to meet the needs of the sizing process. Surfactants have both hydrophobic and hydrophilic groups. When testing cigarette water-based gums with a high content of surfactants, the existing pre-testing metho...
