In this study UV-254nm/H2O2 advanced oxidation process (AOP) was investigated for degrading a model UV absorber compound 2-phenylbenzimidazole-5-sulfonic acid (PBSA) and a structurally similar compound 1H-benzimidazole-2-sulfonic acid (BSA) with a specific focus on their mineralization Overview BLS 99-2 is a liquid benzotriazole UV absorber that provides outstanding light stability to industrial and automotive coatings As a liquid BLS 99-2 blends easily and disperses completely resulting in lower loading requirements and virtually eliminating the particle dispersion problems associated with conventional powder UV absorbers

UV Absorber Market

Ultraviolet (UV) absorber is a material that is used to absorb ultraviolet light and release the energy in the form of heat They are typically used to protect materials by preventing the harmful ultraviolet light from degrading them thus enhancing the performance durability service life and stability of the materials

Qingdao Richkem Co Ltd is a high-tech fine chemical enterprise dedicated in researching and supplying flame retardants and intermediates Based on abundant raw material in Shandong Province Oriented by international demand Richkem aims to combine customers demand and domestic advanced techniques develop market with strict management professional sales team

The molar extinction of UV absorbers of the same class is within very narrow limits practically constant However due to their different molecular weights their extinctions related to the gram differ drastically Thus to reach the same absorption the concentration of UV Absorber 2 can be much lower than that of UV Absorber 1
