Simultaneous detection of morphine and codeine in urine samples of heroin addicts using multi-walled carbon nanotubes modified SnO2-Zn2SnO4 nanocomposites paste electrode

- The SnO2-Zn2SnO4 nanocomposite was prepared via a simple solid state method.
- The structure of the SnO2-Zn2SnO4 was characterized by using XRD, FE-SEM and FT-IR.
- A novel sensor has been developed for Simultaneous detection of MO and CO.
- The method also employed for the determination of MO and CO in biological samples.
