Description
Technical Field
The invention relates to the field of fluorescent whitening agents, in particular to a detection method for rapidly detecting the quality of a fluorescent whitening agent.
Background
The fluorescent whitening agent can absorb ultraviolet rays with the wavelength of 340-380nm and then emit the ultraviolet rays in a very bright and gorgeous fluorescence form in a visible light region of blue-violet light (about 410-460 nm). The blue-violet fluorescence is mixed with yellowish light on the substrate to obtain white light, thereby having whitening effect.
Fluorescent whitening agents applied in the textile, paper and detergent industries mainly comprise two types of triazinyl amino stilbenes and sulfostyryl biphenyl; the fluorescent whitening agent is dispersed in water and then dyed with fibers at different temperatures to whiten the matrix; after different substrates are dyed and dried by simulating a fluorescent brightener under different temperature and time conditions in a laboratory, detecting the CIE whiteness of the whitened substrate and the original substrate by using a whiteness analyzer, and judging the quality of the product by comparing the difference of the CIE whiteness, wherein the method consumes a large amount of manpower energy and generates a large amount of detection waste liquid; therefore, a detection method capable of rapidly detecting the quality of the fluorescent whitening agent is urgently needed.

s3: and detecting the data of the solution obtained in the step S2 by using a spectrophotometer.
Further, the color developing agent is blue dye in step S1, and after being combined with the brightener solution at a specific concentration, the brightener can be triggered to display blue light of a specific waveband, and then the quality of the brightener can be judged by naked eyes, and the physical and chemical values of the brightener can be detected by using a spectrophotometer, so that the method has a very practical effect on quickly judging the quality of the brightener. The compound dye can shield purple light in the whitening agent and enhance blue light according to the whitening theory of the whitening agent, thereby achieving the effect of amplifying the whitening agent.
Further, the mass concentration of the developer solution in step S1 is 0.001 to 0.1%.
Further, in step S2, the fluorescent whitening agent is CBS series, preferably triazinylaminostilbene or sulfostyrylbiphenyl. Further, the fluorescent whitening agent is sodium diphenylethylene biphenyl disulfonate.
