Abstract:Combining with previous research work, by using P507, interference elements, such as Zr and Nb can be effectively separated in silver ICP-MS determination. The method for determing trace silver in the geological samples by using P507separation of loaded polyfoam has been further verified and discussed. Thus, it can be widely used in the industry field, promote testing efficiency and testing technology of Ag and trace elements in geological samples, and realize fast and accurate analysis of trace silver and trace element ICP-MS in geological samples.
