Analysis of molybdenum oxide by inductively coupled plasma atomic emission and mass spectrometry

Procedures for the analysis of molybdenum oxide by of inductively coupled plasma atomic emission spectroscopy (ICP-AES) and mass spectrometry (ICP-MS) are proposed on the basis of preliminary extraction separation of molybdenum from impurity elements. To separate 39 impurity elements (Li, Be, Na, Mg, Al, K, Ca, Sc, Ti, Cr, Mn, Fe, Co, Ni, Zn, Ga, Rb, Sr, Y, Cd, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Pb, Bi, Th, and U), the extraction of molybdenum from hydrochloric acid solutions using 5-n-pentylthio-8-hydroxyquinoline was used. The capacities of both methods ICP-AES and ICP-MS in the analysis of molybdenum oxide analysis were examined without the removal of the matrix and after the extraction separation of molybdenum.
