紫外分光光度法在水中酚标样研制中的应用

An Appliance of UV Spectrophotometry for Preparing Standard Reference Material (SRM) Phenol in Water

利用苯酚碱性水溶液的紫外光吸收特性,按文献记载的摩尔吸收系数和实际测量结果,计算10.00mg/1水中酚的吸收值的标准参考数据,用紫外分光光度法对水中酚标准物质的稳定性和定值数据进行了测量,大大简化了操作手续,并获得了准确的分析结果。

A molar absorptivity from papers as a theoretical value, no a correspondent reference solu-tion, determine UV absorbance and calculate the content of the SRM phenol in water directly.Accuracy and precision of this method are modified greatly at the research of the stability andan accorate value of the SRM.
