摘要
采用马弗炉干法灰化法消化样品 ,火焰原子吸收法连续测定天然香料植物缬草根中微量金属元素 ,检测出K ,Ca ,Na ,Mg ,Fe ,Zn ,Cu ,Co ,Ni,Mn ,Pb等 11种元素 ,其中Fe ,Zn ,Cu ,Co ,Mn ,Ni等 6种人体必需元素 ,加标回收率在 (96 .4～ 10 5 .5 ) %.
Samples are treated by cineration in the muffle furnace and some metal elements are deter mined in the root of Valeriana pseudofficinalis by the flame atomic absorption spectromery.Eleven elements,such as K,Ca,Na,Mg,Fe,Zn,Cu,Co,Ni,Mu,and Pb are detected.Among those elements,six elements of Fe,Zn,Cu,Co,Ni,Mn are necesseny to lives.The rate of reclamation is 96.4%～105.5%
