The detection of morphine and oripavine with acidic potassium permanganate chemiluminescence has been well documented.
The following reaction conditions are commonly employed by our research group; 5 × 10−4 M potassium permanganate in 1% sodium polyphosphate adjusted to pH 2 using orthophosphoric acid and as such these were used in this investigation. However, the solvent system for the separation described above was unsuitable for acidic potassium permanganate chemiluminescence as acetonitrile quenches the
