The secondary mechanisms will be the addition of the compound to your filters that may have the ability to absorb purely natural mild and use it to get started on the degradation system. The principle two regions of investigation are in photocatalytic oxidation[188] and photosensitized degradation.[189] Photocatalytic oxidation employs a species that absorbs radiation and generates hydroxyl radicals that react Together with the filters and begin the breakdown. Photosensitized degradation, while, works by using a species that absorbs radiation and transfers the Strength into the cellulose acetate to start out the degradation process. Both of those processes use other species that absorbed light-weight > three hundred nm to begin the degradation of cellulose acetate.[citation desired]
