Abstract

The invention provides a measurement method for concentration of bisphenol S, and relates to the technical field of chemical analysis and detection. The measurement method comprises the following steps of S1, preparing a blank solution through a sulfuric acid solution, a Fenton reagent and a fluorescent probe solution; S2, preparing multiple standard working solutions through the sulfuric acid solution, the Fenton reagent, the fluorescent probe solution and bisphenol S standard solutions in different concentrations; S3, respectively measuring optical indexes of the blank solution and multiplestandard working solutions, and building a standard curve according to the optical indexes and the concentration of the bisphenol S in the multiple standard working solutions; and S4, measuring an optical index of a to-be-measured sample, and obtaining the concentration of the bisphenol S in a to-be-measured sample according to the optical indexes of the to-be-measured sample and the standard curve. With the measurement method for the concentration of the bisphenol S, provided by the invention, the concentration of the bisphenol S can be rapidly and sensitively measured according to the structure characteristic of sulfuryl contained in the bisphenol and the oxidization characteristics of the Fenton reagent.

Description

technical field [0001] The invention relates to the technical field of chemical analysis and detection, in particular to a method for measuring the concentration of bisphenol S. Background technique [0002] The chemical name of bisphenol S is 4,4-dihydroxydiphenyl sulfone, which has excellent heat resistance, light resistance and oxidation resistance. With the development of science and technology, the application range of bisphenol S is more and more extensive. For example, bisphenol S Phenol S can replace bisphenol A as the main raw material for the production of epoxy resin, polyester resin, phenolic resin, polycarbonate, polyethersulfone and other polymer materials; bisphenol S can be used as an additive to add to various polymer resins To improve the performance of polymeric resin: Bisphenol S can be added to polyester resin to increase the impact strength of polyester resin, added to polyurethane resin as a plasticizer, added to polyvinyl chloride to increase the anti...
