Optimized SPME Method for UV Filter Analysis in River Water

A research paper describes an optimized solid-phase microextraction method using cork as a biosorbent for detecting two UV filters, 4-MBC and OD-PABA, in river water. The method achieved quantification limits of 0.1 and 0.01 µg L-1, respectively, with recovery values between 67 and 107%. The work was authored by Ana C. Silva and published on the PaperswithCode platform.

Use Cases

• Method validation for UV filter detection based on described limits of quantification and recovery values.
• Optimizing solid-phase microextraction parameters based on the pH, time, temperature, and ionic strength factors studied.
• Assessing biosorbent material performance based on the use of cork as an SPME fiber.
• Evaluating analytical reproducibility based on the reported fiber-to-fiber relative standard deviation.

Strengths

• Quantification limits of 0.1 µg L-1 for 4-MBC and 0.01 µg L-1 for OD-PABA.
• Recovery values between 67 and 107% for the developed method.
• Fiber-to-fiber reproducibility with a relative standard deviation lower than 11%.
