Abstract

The invention discloses a method for detecting quinolone in a textile. The method comprises the following steps of sampling; and pretreatment and detection for the content of the quinolone in a pretreated target object, wherein the pretreatment includes the steps of mixing a sample with a first extractant to form a first mixed solution, and carrying out ultrasonic treatment for first designated time at a first preset temperature; and cooling the first mixed solution subjected to the ultrasonic treatment to a second preset temperature. Multiple agents are omitted, so the method is more environment-friendly and more healthy to a human body; the time cost is saved, the pretreatment test process is simple, the instrumental analysis time is short and the consumption for a lot of human and material resources is avoided; with a trace test, a detection limit can be lower, and a test instrument is easily available; and an LC-MS / MS analyzer having the high sensitivity and the strong anti-interference capability is used.

Description

Technical field [0001] The invention relates to the field of detection, in particular to a method for detecting quinoline in textiles. Background technique [0002] Quinoline is a colorless liquid and an aromatic compound. It is miscible with alcohol, ether and carbon disulfide, easily soluble in hot water, but hardly soluble in high cold water. With hygroscopicity, it can absorb moisture from the air to 22% water, and can volatilize with water vapor. Quinoline is used in the preparation of cyanine pigments and photosensitive pigments. Used as organic synthesis reagent, alkaline condensing agent and solvent; used in the printing and dyeing industry to prepare cyanine pigment and photosensitive pigment. [0003] Based on the EU Directive 2018 / 1513 issued by the European Union in October 2018, in the new Article 72 restriction regulations in Annex XVII of the REACH Regulation, quinoline is newly added as a restricted substance in textiles, and the detected content shall not exceed...
