Antimony speciation in spirits stored in PET bottles: identification of a novel antimony complex

Total antimony and its +V and +III oxidation state species were determined in twelve spirit samples (Greek raki and tsipouro) stored in polyethylene terephthalate bottles. Reliable and reproducible results were obtained following direct analysis by using ICP-MS providing total Sb concentrations betw...
