Decoloration

Decoloration refers to the process of removing or reducing the color of a substance. This can occur through various mechanisms, including chemical reactions, oxidation, or physical processes like bleaching. The extent of decoloration can vary, ranging from a slight fading of color to complete removal, leaving the substance colorless or white. It's a common phenomenon observed in a wide range of applications, from textile manufacturing and food processing to environmental remediation and aesthetic treatments. The outcome is often desired for aesthetic or functional reasons, such as increasing the brightness or transparency of a material, or removing unwanted pigments.
