用玻璃纤维滤膜收集空气中的β－萘酚经甲醇解吸．ＯＤＳ柱分离．ＵＶ－２４５ｎｍ检测．高效液相色谱测定β－萘酚时的最低检测浓度为０．００３ｍｇ／ｍ３．在不同浓度时相对标准差均小于１０％．β－萘酚浓度为０～１０．０μｇ／ｍｌ。标准曲线呈线性关系。甲醇对β－萘酚的解吸效率良好，浓度为：３．０、６．７和１０．０μｇ／ｍｌ．β－萘酸解吸效率分别为１００．０、９８．５和９６．３％。以５１／ｍｉｎ的速度采１０ｍｉｎ。平均采样效率为９５．９％，样品在玻璃纤维中最少可稳定７天。空气中可能与β－萘酚共存的萘、间苯二酚：邻苯．甲酸酐在同一色谱图上的分离效果良好。本法具有灵敏度高、操作简单、出峰时间快、样品保存时间长等特点．适合于空气中β－萘酚的测定。
Β-naphthol in the air was collected by glass fiber filter and desorbed by methanol. ODS column separation. UV-245nm detection. The lowest detection concentration of β-naphthol when using high performance liquid chromatography was 0.003mg / m3. Relative standard deviation at different concentrations were less than 10%. β-naphthol concentration of 0 ~ 10.0μg / ml. The standard curve is linear. Methanol had good desorption of β-naphthol at concentrations of 3.0, 6.7 and 10.0 μg / ml. The desorption efficiency of β-naphthalene was 100.0, 98.5 and 96.3% respectively. Take the speed of 51 / min 10min. The average sampling efficiency was 95.9%, and the samples were stable for at least 7 days in glass fiber. Naphthalene, resorcinol: o-benzene, which may co-exist with β-naphthol in the air. Formic anhydride in the same chromatographic separation of good results. This method has the characteristics of high sensitivity, simple operation, fast peak time and long sample storage time. Suitable for air β-naphthol determination.
