Purpose This study assessed the concentrations of platinum (Pt) and palladium (Pd) in surface sediments and sedimentary cores collected from the Pearl River Estuary with a view of evaluating the distribution, background levels, possible sources, and contamination level of anthropogenic Pt and Pd. Materials and methods Thirty-six samples of surface sediments and 12 samples from sedimentary cores...
A simple and rapid analytical method for determining the concentration of rhenium in molybdenite for Re–Os dating was developed. The method used isotope dilution–inductively coupled plasma–mass spectrometry (ID–ICP–MS) after the removal of major matrix elements (e.g., Mo, Fe, and W) from Re by solvent extraction with N-benzoyl-N-phenylhydroxylamine (BPHA) in chloroform solution. The effect on extraction...
