利用紫外——可见分光光度法的基本原理进行定量测定的方法很多.对于单组分的定量测定,可以选择比较简单的经典方法,如绝对法、标准对照法、吸光系数法、标准曲线法等.如果要对多组分混合物的测定而不经预先分离,根据不同的测定情况可以采取等吸收点作图法,Y—参比法、解联立方程组法等. There are many ways to use UV-visible spectrophotometry for quantitative determination.For the quantitative determination of single-component, you can choose relatively simple classical methods, such as absolute method, standard control method, absorption coefficient method, standard curve method If you want to multi-component mixture without the prior determination of the separation, according to different measurement conditions can be used to absorb the points for mapping, Y-reference method, solution of simultaneous equations method.
