Abstract

The invention discloses a detection method of phenolic compounds in a carbonate ester food packaging material and belongs to the technical field of analysis and detection of packaging materials. The detection method comprises the following steps: (1) preparing a standard solution; (2) optimizing liquid chromatographic conditions; (3) optimizing mass spectrum conditions; (4) determining a linear range and detection limit; (5) pre-treating a sample; (6) detecting the sample. According to the detection method disclosed by the invention, a quantitative analysis method for simultaneously determining nonylphenol, octylphenol, cumylphenol and bisphenol A in a polycarbonate material food contact material through a high performance liquid chromatography-tandem mass spectrometry, and the quantitative analysis method is rapid and accurate and has high sensitivity; a pre-treatment step is simple and a simple and reliable analysis method is provided for raw material control and finished-product quality control of production enterprises of wide food-grade contact materials of China.

Description

technical field [0001] The invention relates to the technical field of analysis and detection of packaging materials, in particular to a method for detecting phenolic compounds in carbonate food packaging materials. Background technique [0002] In food contact materials, polycarbonate (Polycarbonate, PC) resin is widely used in baby bottles, space cups, plastic tableware and beverage bottles, drinking In the production of containers such as buckets. [0003] Phenolic compounds are the main industrial raw materials for the production of polymer materials such as epoxy resin, polycarbonate and polysulfone resin. Studies have shown that phenolic compounds in polycarbonate food contact materials are mainly bisphenol A (BPA), p-cumylphenol (CP), nonylphenol (NP), and octylphenol (OP). The Oslo-Paris Convention (OSPAR) has also included nonylphenol and octylphenol in the list of priority pollutants. The United States, Canada, the European Union and China have legislated to pro...
