Abstract:
Paraffin phase spectrophotometry is a new solid phase spectrophotometry. In this paper, RE-8-hydroxyquinoline colour reaction in paraffin phase has been studied. In the medium of NH4Cl-NH3(PH=9.0), the coloured complex of RE-8-hydroxyquinoline can be quantitatively extracted with paraffin. Beer's law is obeyed in the range of 0 to 80ug RE2O3/50ml. The new method has been applied to the determination of micro amount rare earth elements in Sc2O3 with satisfactory results.
