Determination Of Platinum Group Elements In Four New Reference Samples Of Marine Sediments And Nodules By Neutron Activation Analysis After Nickel Sulphide Fire Assay Preconcentration

Platinum group elements were determined in two new reference samples of marine sediments (GSMS-2 and GSMS-3) and in two new reference samples of manganese nodules (GSPN-2 and GSPN-3) by neutron activation analysis after nickel sulphide fire assay preconcentration. Analytical data obtained are presented along with a brief description of the analytical procedure.
