摘要
Abstract
Using a HF-HNO3 system with high-pressure closed digestion,a method to determine concentrations of fifteen rare earth elements (REEs) in marine sediments was studied by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS).The method detection limits were 0.1-7 ng/g.The proposed method was validated by the marine sediment reference materials GBW 07309.The results were consistent with certified values.The determination precision (RSD,n=6) of the sediment samples was less than 2％,and the recoveries were 98％-104.2％.This method has a low detection limit with high precision and accuracy,all of which meet the requirements to analyze a large number of marine sediment samples.关键词
