Abstract:A method for the determination of water-soluble antimony (Ⅲ) and antimony(Ⅴ) in Leigongteng using ultrasound-assisted extraction by hydride generation inductively coupled plasma atomic emission spectrometry was developed in the present paper.Affecting parameters of ultrasound extraction, the pH of antimony species, the operation condition of hydride generation and inductively coupled plasma atomic emission spectrometry were investigated and optimized.The effect of coexisting ions on the determination of antimony was also investigated.The detection limits are 0.3 and 2.4 ng· mL-1 for antimony (Ⅲ) and antimony(Ⅴ), respectively, and with RSD 3.9% for antimony (Ⅲ) and 4.5% for antimony(Ⅴ).The recovery is in the range of 93% to 105%.
