AAS测定不同产地甘草的元素含量
|
摘要
试验中对样品进行了严格的处理采用火焰原子吸收光谱法对不同产地的甘草进行元素测定,得出不同产地甘草最优的生长环境和利用价值.实验中以甘肃、内蒙古、山西三个产地的甘草为原料,用干法灰化及湿法消解的前处理方法,用火焰原子吸收光谱法对其所含的Fe、Mn、Ga、Zn、Cu、Mg六种元素进行测定.研究了干法灰化法工艺中不同产地原料、灰化时间、灰化温度、原料试样质量4个因素和湿法消解工艺中不同产地原料、混酸种类、混酸体积、原料试样质量4个因素对元素含量测定的影响.通过正交试验设计方法确定最佳测定元素含量的最优工艺条件.
In the experiment,the samples were treated with flame atomic absorption spectrometry,and the optimum growth environment and the use value of Glycyrrhiza uralensis Fisch were obtained.In the experiment in Gansu,Inner Mongolia,Shanxi three areas of licorice as raw material,with the pretreatment methods of dry ashing and wet digestion,six kinds of elements in the content of Fe,Mn,Ga,Zn,Cu and Mg were determined by flame atomic absorption spectrometry.Study on the different origin of dry ashing process of raw materials,ashing time,ashing temperature,affecting the quality of raw materials,raw material samples of different origin 4 factors and wet digestion process mixed acid,mixed acid volume,raw material quality sample of 4 factors on the determination of the elements.The optimum technological conditions for determining the optimum content of the elements were determined by orthogonal test design.
