This invention belongs to the field of analytical chemistry technology, specifically relating to a composite indicator and testing method for determining cadmium content in crude cadmium. The composite indicator comprises xylenol orange, thymol blue, and sodium indigo disulfonate, with a mass ratio of xylenol orange, thymol blue, and sodium indigo disulfonate of 1.0–1.5:0.3–0.6:0.5–1.0. This invention utilizes the ternary compound of xylenol orange, thymol blue, and sodium indigo disulfonate, employing the blue background of sodium indigo disulfonate and the reddish-purple and yellow hues of xylenol orange for optical color adjustment. This transforms the color change at the titration endpoint from the traditional reddish-purple to yellow to a bluedish-purple to yellowish-green, significantly increasing the color difference and creating a clear and sharp color change interface, greatly improving the accuracy and reliability of visual endpoint determination.

The invention discloses a batik pigment based on natural plants. The batik pigment comprises the following raw materials: a basic auxiliary agent and at least one color development plant, the basic auxiliary agent is prepared from the following components in parts by weight: 3 to 8 parts of gallnut and 2 to 6 parts of rhizoma curcumae longae; the color development plants comprise the following components in parts by weight: 10 to 20 parts of radix rubiae, 5 to 15 parts of radix scutellariae and 5 to 12 parts of indigo grass.

The application discloses a color rendering control method and a color rendering control system. The color rendering control method comprises the following steps: acquiring first color data; determining second color data according to the first color data; wherein the second color data belongs to a target color space, the target color space comprises four color primaries, and the four color primaries comprise red, blue, indigo and yellow; generating driving data according to the second color data; and driving a color rendering module to work based on the driving data, and rendering color by using color data corresponding to the target color space. Since the indigo primary color is added, in a color gamut diagram corresponding to the target color space, a green region is reduced, more blue regions are increased, and red, yellow, green and blue regions are more uniformly distributed, so that color rendering richness can be significantly improved, and resource waste can be reduced.

The application provides a construction method of a three-color photonic crystal sensor for detecting terramycin in an environment. The steps are as follows: step one, preparing monodisperse silica microspheres with different sizes; and step two, constructing the three-color photonic crystal sensor on the same substrate by a step-by-step vertical sedimentation method. The novel three-color photonic crystal sensor constructed by the application can make the characteristic wavelengths shift to different degrees (R: 867 nm to 921 nm; G: 723 nm to 771 nm; and B: 548 nm to 601 nm), thereby generating three-color transitions (R: light red to red; G: indigo to brick yellow; and B: purple to blue) that can be distinguished by naked eyes, and realizing high-precision visual detection of terramycin in a high ionic strength water environment. Meanwhile, in a logarithmic linear range of 0.1-80 mu g / mL, the R / G / B channels of the three-color photonic crystal sensor have R 2 respectively, and a field structural color change threshold (0.5 mu g / mL) meets water product safety standards. The multi-color photonic crystal sensor provides a new idea for constructing an on-site environment sensor with both laboratory-level quantification and instant visual reading.

The invention belongs to the technical field of pigment synthesis, discloses halogenated ornamental blue as well as a preparation method and application thereof, and breaks through a traditional amino modification-based derivation path of ornamental blue. Halogen is introduced into a main molecular structure of ornamental blue, and 5, 5-dihydroxy ornamental blue reacts with a specific halogenating agent to prepare the blue-light-emitting material. During preparation, 5, 5-dihydroxy blue and a halogenating agent react for 1-2 hours at the temperature of 20-30 DEG C in solvents such as dioxane and acetonitrile according to the molar ratio of 1: 1-1: 3, and a product can be obtained through ice water quenching, filtering, washing and drying. The synthesis method is simple and convenient, and post-treatment is simple. The halogenated ornamental blue is excellent in dyeing performance, the K / S value exceeds 10, the dye uptake exceeds 91%, and the color fastness to sun, washing and wet rubbing reaches level 5, which is obviously superior to that of lemon yellow and 5, 5-dihydroxy ornamental blue, so that the halogenated ornamental blue not only can be used for dyeing, but also can be used as an intermediate for synthesis of other derivatives, and the family structure and the application scene of the ornamental blue are enriched.
