摘要:
The disclosure relates to a method for decolorization of a dye-colored synthetic polymer, which includes the steps of treating a dye-colored synthetic polymer, such as polyester, with a treatment composition at pH 4 or less, the treatment composition comprising hydrogen peroxide, an iron catalyst, water, and a ketone. The resulting decolorized synthetic polymer is then separated from the treatment composition.
