Electrochemical determination of Sudan IV in food samples by using graphene-modified glassy carbon electrodes

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

A simple and sensitive modified electrode was fabricated with graphene via the drop-casting method and applied for the electrochemical detection of Sudan IV. Cyclic voltammetry (CV) was used to investigate the electrochemical behaviors of Sudan IV in phosphate buffer solution (PBS). The experimental conditions such as determining medium, scan rate, and accumulation time were optimized for the determination of Sudan IV. |
