Abstract

The nickel and vanadium contents of nine institutional diets were determined by atomic absorption spectrometry with background correction. The following values were obtained for nickel: mean concentration, 0.27 +/- 0.02 microgram/g (dry weight); range, 0.19 and 0.41 microgram/g; mean intake, 165 +/- 11 microgram/day or 75 +/- 10 microgram/1000 cal. The respective values for vanadium were: 0.032 +/- 0.004 microgram/g (dry weight); 0.019 to 0.050 microgram/g; 20.4 +/- 2.3 microgram/day or 8.9 +/- 1.0 microgram/1000 cal. Thus, vanadium is present at approximately one order of magnitude less than nickel.

摘要

采用带背景校正的原子吸收光谱法测定了九种机构饮食中的镍和钒含量。镍的测定结果如下：平均浓度为0.27±0.02微克/克（干重）；范围为0.19至0.41微克/克；平均摄入量为165±11微克/天或75±10微克/1000卡路里。钒的相应值为：0.032±0.004微克/克（干重）；0.019至0.050微克/克；20.4±2.3微克/天或8.9±1.0微克/1000卡路里。因此，钒的含量比镍低约一个数量级。
