chemical analysis of liquid color cie1976l * a * b * Color space measurement method

Abstract

The invention provides a CIE1976L*a*b*color space determination method for chemical analysis of the color of liquid, and belongs to the technical field of measurement. The CIE1976L*a*b*color space determination method for chemical analysis of the color of liquid at least includes the step that two or more chemical reagents are added into a reaction vessel so that a chemical reaction can happen and the color can change after the reaction. The CIE1976L*a*b*color space determination method for chemical analysis of the color of liquid is characterized in that a color space method is used for measuring the changing process of the color of chemical reaction liquid. By means of the CIE1976L*a*b*color space determination method for chemical analysis of the color of liquid, digitized measurement of the color of chemical reaction liquid is achieved, measurement steps are simple, and automatic and batched large-scale detection can be achieved.

Description

technical field [0001] The invention relates to a chemical analysis liquid color CIE1976L * a * b * The invention relates to a method for measuring a color space, belonging to the technical field of measurement. Background technique [0002] In wet chemical analysis, the measurement of solution reaction process is an extremely important basic work in chemical analysis. The accuracy of its measurement determines the accuracy of other detection results, and it is an indispensable and important link in wet chemical analysis. [0003] At present, the determination and description of the color change representing the reaction process in domestic and foreign chemical wet analysis is the artificial visual method, which is the instant color of the reaction process according to the visual method "visual experience→thinking judgment→language description". Changes are described in language, and the meaning of color adjectives representing the reaction process is up to the operator t...

AI Technical Summary

Problems solved by technology

[0007] 3) For information transmission, the sensory understanding of color can only be determined by face-to-face teaching by master and apprentice;

[0008] 4) The reaction process can only be described in words, there is no numerical information, it cannot be transferred by value, and it is difficult to trace back;

[0009] 5) It is greatly affected by the environment, labor-intensive, and prone to visual fatigue;

[0010] 6) The test steps are cumbersome, and it is impossible to realize automated and batch detection scale
