摘要
本文研究了用荧光分光光度法直接测定环境水中苯酚和十二烷基苯磺酸钠（ＳＤＢＳ）二种水中污染物。在ｐＨ〉１１直接测定ＳＤＢＳ含量，波长为λｅｘ／λｅｍ＝２３０／２９５ｎｍ，检出限４．４ｎｇ／ｍＬ，线性范围０￣２．２μｇ／ｍｌ。在ｐＨ＝６，波长为λｅｘ／λｅｍ＝２３０／２９５ｎｍ，测得二者合量，从合量中减去ＳＤＢＳ含量即得苯酚含量，检出限４．０ｎｇ／ｍｌ，线性范围０￣０．８５μｇ／ｍＬ。
The direct determination of both phenol and sodium dodecyl benzene sulfonate (SDBS) in environmental water by fluorescence spectrophotometry was reported. As the wavelength of λex/λem is 230/295 nm at pH>11, SDBS content is determined with a lowest detection limit of 4. 4 ng/mL and a linear range of 0-2. 2 μg/mL. As the wavelength of λex/λem is 230/290 nm at pH 6, the total quantity of SDBS and phenol is determined, then the content of the phenol by subtracting SDBS from the total quantity is obtained with a lowest detection limit of 4. 0 ng/mL and a linear range of 0-0. 85 μg/mL. The recovery is achieved between 99% and 101% with satisfactory results.
