查询词典 platinum process

The literature about the synthesis of the ion exchange and chelating adsorbents used in the off-line separation and preconcentration of the noble metals and the development of the on-line microcolumn separation and preconcentration of the noble metals were reviewed. Four silica gel-based adsorbents with rhodanine, 2-mercaptopyrimidine, 2-mercaptothiazoline and isophenylthiourea as the functional groups were first synthesized and applied to the on-line separation and preconcentration of silver, gold, palladium and platinum for their FAAS determination.
