摘要
利用原子吸收光谱法研究隆回富硒区野生水芹中Ca、Mg、Fe、Se、Zn、Cu六种元素的含量。结果表明:隆回富硒区野生新鲜水芹菜中Zn、Cu、Fe、Mg、Ca、Se分别达到1.4277×10-4、0.7853×10-4、90.4767×10-4、321.8782×10-4、1313.3938×10-4、1.46×10-4μg/g,水分含量为13.4%的干水芹菜中含量分别为69.01、9.42、1066.38、3540.66、14312.92、0.154μg/g。除Zn的含量低于芹菜外,其它各元素的含量均高于所列的常见蔬菜,其中Fe含量是普通蔬菜的45～7.5倍、Ca含量是普通蔬菜的13-1.6倍、Se含量是普通蔬菜的9.7～2.4倍。
The content of Ca, Mg, Fe, Se, Zn, Cu of wildness cress in Se-enriched area in Longhui was detemined by method of atomic absorption spectrometry. The results showed that the content of Zn, Cu, Fe, Mg, Ca, Se is 1.4277×10^-14,0.7853 ×10^-4, 90.4767× 10^-4, 321.8782×10^-4, 1313.3938× 10^-4, 1.46 ×10^4μg/g in fresh cress, and 69.01, 9.42, 1066.38, 3540. 66, 14312.92, 0.154vg/g in day cress（water content is 13.4%）. Except the content of Zn lower than celery, others element＇s content all higher than other common vegetables. The content of Fe is 45 to 7.5 times to common vegetables. The content of Ca is 13 tol. 6 times to common vegetables. The content of Se is 9.7 to 2.4 times to common vegetables.
