title: A new preconcentration method for platinum and gold based on a macropore anion resin HHY-10A.
abstract: The ion exchange behavior of Au and Pt on a new China-made macropore anion resin was studied using radiotracer technique. The conditions for adsorption and desorption, such as acidity, flow-rate and concentration of desorbing agents were studied carefully. Using the established method, the contents of Au and Pt in two Chinese ultrabasic SRMs were determined by ICP-MS and the results found in good agreement with the reference values.
