Abstract-The deposition of needle-shaped cuprous oxide
Cu2O is easy to aggregate or be oxidized to Cu ( ) irons.
(Cu2O) particles (20~50 nm) on chitosan nanoparticles were
made by anodic oxidation of copper electrode in alkaline Furthermore, Fe sludge disposal and/or regeneration after the
solution, Fe2+ was immobilized by chitosan nanoparticles with Fenton reaction are also a serious problem during pollutant

chelating. Chitosan-Fe /Cu2O were used as an immobilized degradation in homogeneous media. The present regulation
Fenton reagent activated by visible light at patible pH allowing an iron upper limit of mg/L [7], makes the use of
values(pH≈7-8) in the degradation of brilliant red X-3B without Fe irons as in homogeneous solution as practiced until now
adding H2O2. The results indicated that the effect of this novel needing removal at the end of the treatment. This is expensive
