A method for the simultaneous determination of five OTCs
in the sediment samples by HPLC-ICP-MS was developed in
the present work. The detection limits of OTCs were lower
than 0.5 ȝg L
–1
for each Sn species. The international standard
reference PACS-2 samples were treated by supersonic
extraction with mobile phase added 0.2% tropolone. The
results showed good accordance with the certified values. The
pretreatment method was rapid, simple, and available for
sediment organotin speciation analysis.
