چکیده    Sponge-like porous cerium oxide particles were prepared through the self-propagatinghigh-temperature synthesis process. then, the synthesized powder was used to modifythe carbon paste electrode (cpe/porous ceo2) for voltammetric determination of uricacid (ua) in biological fluids. under optimal conditions, the linear concentrationresponserelationship was in the range of 0.25-10 and 10-300 μm, and a detection limitof 60 nm (s/n=3) was obtained. in addition, the proposed sensor showed excellentselectivity towards ua over common co-existing species such as ascorbic acid,ibuprofen, dopamine, and acetaminophen. good repeatability of sensor responses(relative standard deviation (rsd) < 3.2%), superior reproducibility (rsd < 2.8%),and excellent storage stability (error < 5% after 1 month storage at room temperature)along with appropriate recovery values (in the range of 99.2 -102.7%) demonstrate theapplicability of cpe/porous ceo2 for the determination of ua levels in biological fluids.
