| Abstract: | A method of polyacrylic acid-complexation and ultrafiltration for matrix modification and inductively coupled plasma mass spectrometry(ICP-MS)was developed for the determination of 24 trace level of rare earth elements(REEs) and metal elements in coastal and estuarine seawater.REEs ions,Cu2+,Pb2+,Cd2+,Co2+,Ni2+ could reacted with polyacrylic acid(PAA) to form stable complexes when the pH value was above 7.5,which could be separated and enriched absolutely after trapped and eluted from the ultrafilter.Full q... |
