摘要
采用冻干法-全量酸消解-火焰原子吸收光谱法测定畜禽粪便中铜和锌,优化了试验条件。铜和锌分别在0 mg/L^3.00 mg/L和0 mg/L^1.00 mg/L范围内线性良好,检出限分别为6 mg/kg和2 mg/kg(按取0.5 g试样消解定容至50 mL计算),粪便试样测定的RSD分别为1.3%和3.7%,加标回收率分别为104%和107%。
The method of freeze drying-total acids digestion-flame atomic absorption spectrophotometry was established for determination of Copper and Zinc in the poultry and animal feces. The experimental conditions were optimized to produce the following results ： good linearity of Copper in the range from 0 mg/L to 3.00 mg/L and Zinc in the range from 0 mg/L to 1.00 mg/L, the detection limits of Copper 6 mg/kg and Zinc 2 mg/kg （0.5 g sample digested in 50 mL solution） , the RSDs of the poultry and animal feces samples of Copper 1.3% and of Zinc 3.7% , the recoveries of Copper 104% and of Zinc 107%.
