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 upon contact with hot or fatty material. A 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 200-300nm. The λmax of polystyrene was found to be 261.5nm. The method was linear for the polystyrene concentration ranging from 20 to120µg/mL. The limit of detection was founded to be 1.65µg/mL, and the limit of quantification was 5µg/mL. Interday and intraday precision were performed for the developed method, and the RSD was less than 2%. Further, the developed method was evaluated with other ICH parameters, such as ruggedness and robustness, showing positive results. The developed UV spectrophotometric method would be useful for estimating polystyrene plastic or microplastic in polluted water in a cost and time-efficient manner.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Microplastic,Polystyrene,UV spectrophotometer method,White pollution.</Keywords> <URLs> <Abstract>https://isfcppharmaspire.com/ubijournal-v1copy/journals/abstract.php?article_id=14699&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/> </References> </Journal> </Article> </ArticleSet>
