Determination of rhodium: Since the origins until today ICP-OES and ICP-MS.
Rh is contained in catalyst in much smaller quantities than Pt. For this reason, the database for this metal with respect to emissions from catalytic converters is much smaller than that for platinum, thus precluding a quantitative risk assessment. Accurate determinations of the rhodium have always been difficult tasks. The metal is often present at trace levels in sample types of complex composition. This situation has improved recently due to developments of instrumental methods and their applications to analyses of rhodium in a variety of matrices. The purpose of this review is to describe the analytical sensitive methods by inductively coupled plasma spectrometry.
