title: [Studies on the quantitation of trace elements in complex prescription decoctions of ochre and calcined ochre].
abstract: The present paper reports the determination of Fe, Cu, Zn, Mn and As in complex prescription decoctions of ochre and calcined ochre by atomic absorption spectroscopy. The experimental result shows that in most complex prescription decoctions the contents of Fe, Mn and As are lower in these with calcined ochre than with ochre. The contents of Zn and Cu are higher in the decoctions with calcined ochre than those with ochre.
