GB/T 43108-2023 "Dyes — Determination of solubility in organic solvents — Gravimetric method and photometric method" specifies the use of the gravimetric method and the photometric method to determine the solubility of dyes in organic solvents. The gravimetric method calculates solubility by weighing the mass of undissolved dye, while the photometric method determines solubility by measuring the absorbance of the dye solution based on the Lambert-Beer law. The standard clarifies the reagent selection, instrument and equipment requirements, sample preparation procedures, and result calculation methods for both approaches, and is applicable to the determination of solubility for various dyes in specified organic solvents.
