Abstract
Platinum nanoparticles (PNP) were deposited on the Pt disk electrode by electrochemical deposition, it was found that salicylic acid (SA) had good electrocatalytic oxidation response at the prepared Pt nanoparticles modified Pt disk electrode (PNP/Pt). Then the modified electrode was used to detect SA in weak alkali condition, it was found that the response current was 9.2 times that of bare Pt disk electrode, and the linear range of detection was 2.0 × 10−5 to 5.0 × 10−4 M. After that, the electrode was adopted to detect the SA in Zuguangsan, one kind of Chinese medicine, the results showed that the PNP/Pt electrode has low detection limit, high repeatability and stability as SA sensor, could be applied in the detection of SA reliably.
