摘要
本文研 究了用荧光分光 光度法测定 环境水中 苯酚和邻 羟基苯甲 酸的含量, 在 p H> 11 时直接测 定邻羟基苯甲酸的含量,波长为 λex /λe m = 289/338n m ,检出限为3.4ng /m L,线性范 围0—6.0μg/m L。在 p H= 6,波长 为 λex /λe m = 270/297nm 测得 苯酚 含量, 检 出限 为4. 0n g/m L, 线性 范围 在 0—0.85μg/m L,回 收率 为98% —101% ,结果满意。
The direct determination of phenol and o hydroxybenzoice acid in environmental water by fluorescence sepectrophotometry was reported.As the wavelength of λ ex / λ em is 289/338nm at pH>11, o hydroxybenzoic acid content is determined with a lowest detection limit of 3.4ng/mL.As the wavelength of λ ex / λ em is 270/297nm at pH=6,phenol content is determined with a lowest detection limit of 4.0ng/mL and a linear range of 0—0.85μg/mL.The recovery is achieved between 98% and 101% with satisfactory results.
