However, polystyrene can be categorized as a potent carcinogenic due to its monomer unit. Polystyrene comprises several styrene units that easily leach as styrene microplastics on contact with hot or fatty material. A ultraviolet (UV) spectrophotometer method has been developed for the determination of polystyrene. Polystyrene in an aqueous solution with tetrahydrofuran was estimated at a wavelength ranging from 200 to 300 nm. The __ampersandsignlambda;max of polystyrene was found to be 261.5 nm. The method was linear for the polystyrene concentration ranging from 20 to 120 __ampersandsignmu;g/mL. The limit of detection was founded to be 1.65 __ampersandsignmu;g/mL, and the limit of quantification was 5 __ampersandsignmu;g/mL. Interday and intraday precision were performed for the developed method, and the RSD was</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Microplastic, Polystyrene, Ultraviolet spectrophotometer method, White pollution</Keywords> <URLs> <Abstract>https://isfcppharmaspire.com/ubijournal-v1copy/journals/abstract.php?article_id=14651&title=Development and validation of simple UV-spectrophotometric method for the estimation of polystyrene plastic/microplastic</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References>1.
