Surfactant identification method and identification equipment based on solid surface wettability characteristics

Abstract

The invention discloses a surfactant identification method and identification equipment based on solid surface wettability characteristics. The method comprises the steps of: building a surfactant identification criterion database by acquiring the wettability characteristic parameters of a plurality of known surfactant solutions on the surface of the same solid and obtaining the preconditions of the wettability characteristic parameters, the preconditions comprising solvent types, surfactant solution concentration, solid surface material types and angles, shooting parameters of shooting imaging equipment and image processing parameters; determining a precondition for identifying a to-be-identified surfactant, preparing a to-be-identified surfactant solution, and acquiring an identificationcriterion of the to-be-identified surfactant; and comparing the acquired identification criterion of the to-be-identified surfactant with data in the surfactant identification criterion database so as to realize identification of the to-be-identified surfactant.

Description

technical field [0001] The invention belongs to the technical field of substance identification, in particular to a surfactant identification method and identification equipment based on the wetting properties of solid surfaces. Background technique [0002] There is a huge demand for substance identification in all walks of life, and many substance identification methods have also been proposed at present, such as patent 1 (H. Fuhesi, T. Friedrich, W. Schlepp. The method for identifying active substances [ P]. Germany: CN1231728, 1999) proposed to use the signal change observed by scanning optical near-field microscope equipment to detect active substances. However, this method requires expensive equipment and requires professional operation. Patent 2 (Zhu Tuo, Ni Xiaowu, Chen Guoqing, Gao Shumei, Yu Ruipeng, Xu Hui, He Haijian, Gu Endong. A method for identifying alcohols by fluorescence spectroscopy [P]. Jiangsu: CN101042344, 2007) provides a A method of using fluoresce...

AI Technical Summary

Problems solved by technology

Sichuan: CN101566569, 2009) for the identification method of two fluorescent spectrum mixing substances at present, there is inefficiency, the identification cost is higher and the accuracy is affected by the subjective factors of personnel, etc., providing a kind of identification of multiple fluorescent spectrum mixing substances by characteristic parameters. Systems and methods for stacking matter

This method requires complex equipment, computational processing methods and complex operations

Looking at these methods, the more consistent feature is that they basically require the use of expensive and specialized instruments such as mass spectrometers, chromatographs, and spectrometers, which are not conducive to simple and economical substance identification.
