| 摘 要： | 采用FAAS法对食用菌中微量元素 Ca、Mg 的含量分别在无释放剂和加入锶盐和镧盐作释放剂条件下进行了测定.结果发现,加入锶和镧盐均能提高大多数试样 Ca、Mg 元素含量的测定灵敏度,且镧盐的释放效果明显高于锶盐,但有个别反常现象.对比锶盐和镧盐作释放剂条件下的测定结果和加标回收率,也表明镧盐作释放剂的回收率更接近100%.

| Abstract: | Trace elements of Ca and Mg content in mushroom was determined without release agents and with Sr and La salt release agents by using AAS method.The result shows that adding Sr and La salt will improve sensitivity of most experimental specimen of Ca and Mg,the releasing effect of La salt is apparently higher than that of Sr salt,but there are exceptional abnormal phenomena.The determination result compared under the condition of release agents of Sr and La and the recovery rate with added specimen shows that the recovery rate of La salt as releasing agent more closely approaches 100%. |
