Abstract

The invention discloses a rapid detection method of alkylphenol ethoxylate on the basis of ion mobility spectrometry. The rapid detection method comprises steps as follows: (A), manufacture of an ion sputtering coating capillary tube spray ionization device: the manufacture comprises preparation of a coated borosilicate glass capillary tube and assembling of the ion sputtering coating capillary tube spray ionization device; (B) rapid detection with ion mobility spectrometry: a to-be-detected sample solution is transferred to the coated borosilicate glass capillary tube, the coated borosilicate glass capillary tube is put at the front end of an electric spray sample injection port of an ion mobility spectrometry host, parameters of the ion mobility spectrometry host are set, a sample is ionized and detected by a Faraday cup detector after being separated in a migration tube, and corresponding graphs are obtained. By means of the rapid detection method of alkylphenol ethoxylate on the basis of ion mobility spectrometry, the detection cost is greatly reduced and the detection efficiency is improved while the data detection accuracy is ensured, and the possible rapid alkylphenol ethoxylate detection method is provided for real-time online detection.

Description

technical field [0001] The invention relates to a detection method, in particular to a method for rapidly detecting alkylphenol polyoxyethylene ether based on ion mobility spectrometry. Background technique [0002] Alkylphenol polyoxyethylene ethers are widely used in textiles, plastics, rubber, daily chemicals, medicine, papermaking, electronics and other fields. They are mainly used as textile auxiliaries, detergents, emulsifiers, wetting agents, stabilizers, etc. Another large class of nonionic surfactants following fatty alcohol polyoxyethylene ethers. Among the alkylphenol polyoxyethylene ethers, nonylphenol polyoxyethylene ether is the most, accounting for 80-85%, and octylphenol polyoxyethylene ether accounts for about 15%. As an endocrine disruptor, the biodegradable metabolites of alkylphenol ethoxylates will accumulate in the organism and enter the human body through the food chain cycle, which will have a serious impact on the growth of human cancer cells and re...
