Extraction of Pregabalin in Urine Samples Using a Sulfonated Poly(ether ether ketone) Membrane
International Journal of Analytical Chemistry, 2021 In this work, a simple polymer-assisted microextraction technique was developed to determine pregabalin (an anticonvulsant drug) in the urine sample. A sulfonated poly(ether ether ketone) membrane was used as a sorbent for pregabalin extraction, and the ...
