摘要: 以胡萝卜为碳源，氢氧化钾为活化剂，制备生物质碳材料(PCMC)。以PCMC修饰玻碳电极，用于对乙酰氨基酚的测定。结果表明：在0.01 μM~50 μM范围内，对乙酰氨基酚的浓度与电流呈现良好的线性关系，检测限为6.18 nM。可能是由于活化剂氢氧化钾的引入，与部分生物质碳反应，使得材料的比表面积增大，结合的位点增多，从而增强了对对乙酰氨基酚的电化学响应。
Abstract: Biomass carbon material (PCMC) was prepared with carrot as carbon source and potassium hydroxide as activator. The PCMC modified electrode was prepared for the determination of acetaminophen. The results showed that the concentration of acetaminophen showed a good linear relationship with the current in the range of 0.01 μM~50 μM, and the detection limit was 6.18 nM. It might be ascribed to the reaction between activator potassium hydroxide and biomass carbon, which increased the specific surface area of the material and the number of binding sites, thus enhanced the electrochemical response to acetaminophen.
