摘要：

A method is described for the determination of Cd and Zn isotope ratios in sheep's blood and organ tissue. Samples were digested with nitric acid using a microwave oven. Cadmium and Zn were separated from matrix components using adsorption chromatography prior to isotope ratio measurement by electrothermal vaporization inductively coupled plasma mass spectrometry. A concentration factor of 35 was achieved. Limits of detection for the determination of Cd and Zn in blood were 0.34 and 0.40 pg g-1, respectively. Cadmium isotope ratios (Cd-111 : 106Cd; Cd-111 : Cd-110) were determined with a precision of 2-3% for both peak height and area count measurements. Zinc isotope ratios (Zn-68 : Zn-67; Zn-68 : Zn-66) were determined with a precision of 2% for peak height measurements and 1% for peak area count measurements.
