| 摘 要： | 生物样品用灼烧法，除去有机物，在浓度为5％的盐酸介质中，加入EDTA和铵盐作为基本改进剂，清除石墨炉原子吸收法测定钒时铜、铁离子的干扰，可直接测定钒．采用标准加入法回收率为96．4-106．8％，相对标准偏差3．95％。

| Abstract: | The organic materials removed from biosamples by using ignition method, in hydrochloric acid medium that consistency is 5%, EDTA, ammonium salt are added as a basic improver, eliminating the disturbance of copper and iron ion by graphite furnace atomic absorption spectroscopy, we can directly determine V. The recovery percent is 964%~1068% with a deviation of 3.95%. |
