| 摘 要： | 根据实验得出的乙二醛、乙醛酸、草酸三组分混合物中各组分在特定波长下呈现出的良好的线性关系,建立起三组分质量浓度与混合吸光度的回归方程组,形成了多波长线性回归-矩阵法,实现了乙二醛氧化制备乙醛酸体系中反应产物乙二醛、乙醛酸、草酸含量的同时测定.研究结果表明:当乙二醛检测下限为1.024 mg/L时,回收率为94%~98%...

| Abstract: | According to the experimental results,in three components glyoxal,glyoxylic acid and oxalic acid in the mixture presented the good linear relationship at the specific wave length.The regression equations between mass concentrations of the three components and the mixed absorbances were established;the multi-wave length linear regression-matrix method was formed;the simultaneous determination of the amounts of glyoxal,glyoxylic acid and oxalic acid from the product which glyoxal was oxidized to glyoxylic aci... |
