摘要：
A high sensitive carbon paste electrode modified with NiO/CNTs and ionic liquid (ILs/NiO/CNT/CPE) was describe for voltammetric determination of quercetin. Compared to unmodified carbon paste electrode, the electrochemical response was greatly improved for quercetin electrooxidation. Result shows, the oxidation peak current was increased to about 6.5 times at the surface of ILs/NiO/CNT/CPE compared to CPE. The linear response range and detection limit were found to be 0.08-400 mu M and 0.03 mu M, respectively. ILs/NiO/CNT/CPE was successfully applied for the determination of quercetin in real samples such as onions, apple and capsule. The results showed that the proposed method is highly selective, sensitive with a fast response for quercetin analysis.
