Sulfur dioxide urea is a chemical substance commonly used in the production of dyes and pigments. If you need to strip or remove sulfur dioxide urea dye or pigment, you can try the following methods:

Solvent dissolution method: Choose a suitable organic solvent (such as alcohols, ketones, ethers, etc.) and dissolve the sulfur dioxide urea in it. Stirring or ultrasound treatment can ensure sufficient contact between the solvent and the dye or pigment, thereby achieving stripping effect.

Rinsing method: Use appropriate solvents (such as water, organic solvents, etc.) for repeated rinsing of the dye or pigment. You can try adjusting the temperature and concentration of the solvent or using different rinsing agents to improve the removal effect.

Chemical stripping method: Based on the chemical properties of sulfur dioxide urea dye or pigment, select the corresponding chemical agent for stripping. For example, if the dye or pigment is sensitive to alkaline environments, you can try using an alkaline solution for stripping. If it is sensitive to acidic environments, an acidic solution can be used.
