Porous Carbon Modified Electrode as a Highly‐sensitive Electrochemical Sensing Platform for Salvianolic Acid B

Abstract

Porous carbon (PC) was prepared via nanocasting strategy, and used to modify the surface of glassy carbon electrode (GCE). The modification of PC obviously increases the surface accumulation ability of GCE, and consequently enhances the oxidation signals of salvianolic acid B greatly. As a result, a novel electrochemical determination platform was developed for salvianolic acid B. The linear range was from 5 to 1000 μg L−1, and the detection limit was 1.16 μg L−1. It was used in the sample analysis of traditional Chinese medicines, and the accuracy was satisfactory.
