Abstract

The invention discloses a method for measuring hydrogenated terphenyl, comprising the steps of: performing sampling; performing pre-treatment and detecting the content of the hydrogenated terphenyl ina target object subjected to the pre-treatment, wherein the pre-treatment comprises the steps of: mixing a sample with a first extracting agent to form a first mixing liquid, and performing ultrasonic treatment at a first designated temperature for a first preset time; mixing the first mixing liquid with a second extracting agent to form a second mixing liquid, and performing ultrasonic treatmentat a second designated temperature for a second preset time. The method of the invention has the beneficial effects that: multiple reagents are reduced, thus the method is environment friendly and healthy for human body; a detection limit is low, operation is simple and promotion performance is strong; a test instrument can be obtained easily, a GC-MS (Gaschromatographic-Mass Spectrometry) analyzer is used, and the GC-MS analyzer is high in sensitivity and good in anti-interference capability.

Description

technical field [0001] The invention relates to the detection field, in particular to a method for determining hydrogenated terphenyls. Background technique [0002] Terphenyl hydrogenated (abbreviation: TPHG, CAS No.: 61788-32-7) is a broad-spectrum, high-efficiency, low-cost industrial additive, which has excellent thermal stability, oxidation resistance and low vapor pressure The high-temperature heat transfer oil is widely used in petrochemical, plastic rubber, leather textile, wood processing, paper printing and other fields, and acts as a heat source for high-temperature heating production processes. At present, the annual output of hydrogenated terphenyls in Europe is about 1,000-10,000 metric tons; with the development of my country's industrial technology and the improvement of production levels, the output of hydrogenated terphenyls is also increasing year by year. [0003] However, in April 2018, the European Union issued an announcement announcing that hydrogena...
