Electrochemical detection of toxic ractopamine and salbutamol in pig meat and human urine samples by using poly taurine/zirconia nanoparticles modified electrodes

- A novel poly taurine/ZrO2 nanocomposite film was developed at physiological pH conditions.
- Effective electrooxidation adsorption signals for the detection of salbutamol and ractopamine.
- Real sample application.
- Sufficient enough peak separation around 0.30 V for uric acid and salbutamol.
- The electrode possesses good stability, reproducibility, sensitivity and wide linear range.
