GB/T 23977-2009 "Dyes—Determination of salt content—Conductivity method" specifies a method for determining the salt content in dyes using the conductivity method, applicable to various dye products. The principle relies on the conductive properties of ionic salts. After dissolving the sample, the conductivity of the solution is measured using a conductivity meter, and the salt content is calculated based on a standard calibration curve. The test requires instruments such as a conductivity meter, analytical balance, and volumetric flasks, offering a simple and rapid operation that provides an efficient means for quality control in dye production.
