Determination of precious metal in metal support catalytic converter for motorcycles
1 Scope
This standard specifies the preparation of test solution of precious metal elements such as platinum (Pt), palladium (Pd) and rhodium (Rh) in metal support catalytic converter for motorcycles (including mopeds) and the determination by inductively coupled plasma-atomic/optical emission spectrometry (ICP-OES/AES), inductively coupled plasma mass spectrometry (ICP-MS) and (atomic absorption spectrometry) AAS.
It is applicable to the determination of precious metal in metal support catalytic converter for motorcycles.
