The secondary mechanisms could be the addition of the compound towards the filters that may have the capacity to soak up pure light-weight and utilize it to start out the degradation method. The key two areas of research are in photocatalytic oxidation[118] and photosensitized degradation.[119] Photocatalytic oxidation takes advantage of a species that absorbs radiation and makes hydroxyl radicals that respond Together with the filters and start the breakdown. Photosensitized degradation, although, uses a species that absorbs radiation and transfers the Electrical power to your cellulose acetate to start out the degradation method. Each procedures use other species that absorbed light-weight > three hundred nm to begin the degradation of cellulose acetate.[citation needed] Alternative and remediation initiatives
