1测定原理每种元素原子受激发时发射出一定特征的光谱线,不同元素具有不同的特征光谱线,其强度随着元素含量的增加而增强,因此通过测定特征光谱线的强度就可间接地测定元素的储量。2实验2.1实验方法所采用的实验方法为标准曲线法,即用纯试剂配制成各种浓度标准溶液后先测定其光谱线的强度,绘出浓度与光谱强度的标准曲线,然后测定未知浓度样品的光谱强度并通过曲线查出样品的浓度。2.2实验仪器
1 Determination principle Each element of the atom excited by the emission of a certain characteristic spectral lines, different elements have different characteristic spectral lines, the intensity increases with the increase of elemental content, so by determining the intensity of the characteristic spectral lines can be indirectly Determination of the elemental reserves. 2 Experimental 2.1 Experimental methods used in the experimental method for the standard curve method, which uses pure reagent formulated into various concentrations of standard solution after measuring the intensity of the spectral line, draw a standard curve of concentration and spectral intensity, and then the determination of unknown concentration samples Of the spectral intensity and through the curve to detect the concentration of the sample. 2.2 Experimental equipment
