Abstract
This research report presents a novel and sustainable method for removing microfibers, a
type of microplastic, from washing machine sewage. The study focuses on polyester microfibers,
which are released into the environment during the washing of synthetic clothing and have
negative impacts on aquatic organisms and ecosystems. The proposed method combines Fenton
reaction pretreatment and electro-sorption to effectively target the ester bonds in polyester
microfibers and increase their electrical distribution homogeneity. Under optimized experimental
conditions, including a Fe(NO

This research report presents a novel and sustainable method for removing microfibers, a

which are released into the environment during the washing of synthetic clothing and have

2 concentration of 1.96 M,
temperature of 25°C, pretreatment time of 30 minutes, electrode of nickel foam for cathode and
carbon rod for anode, NaCl concentration of 3.5 g/L, applied voltage of 4 V, and electrosorption
time of 30 minutes, the method achieved a recovery rate of up to 97%. The recovery rate was
calculated by mass difference. The results demonstrate that the proposed method is highly
effective in removing polyester microfibers and offers a potential solution to the problem of
microfiber pollution in the environment. The method has potential for implementation in a real-world
laundry setting and can contribute to the development of more effective and sustainable
wastewater treatment technologies.
