中文摘要：

以合成的β-环糊精交联树脂为吸附剂,紫外可见光谱分析微量对硝基酚。在碱性条件下,考察了对硝基酚在β-环糊精交联树脂上的吸附行为。在0.02mol/L NaOH介质中,室温下吸附30min,树脂能有效分离富集对硝基酚,以甲醇-水（1∶1,V/V）溶液为洗脱液,树脂能重复利用。此方法线性范围是0.5～90mg/L,检出限为0.15mg/L,测定结果令人满意。

英文摘要：

The β-cyclodextrin cross-linked polymer（β-CDCP） was used as adsorbent to pre-concentrate/separate the trace p-nitrophenol and then the determination was carried by UV-Vis spectrophotometry. Under alkaline condition, the adsorption/elution behavior of p-nitrophenol was studied. In 0.02 mol/L NaOH solution and at room temperature for 30 min, the resin could separate and pre-concentrate the p-nitrophenol effectively. Methanol solution（ 1：1, V/V） was used as eluent and the β-CDCP could be used repeatedly. The linear range and detection limit was 0.5 -90.0 mg/L and 3.10 μg/L, respectively. The proposed method has been used to determine the p-nitrophenol in synthesized sample with satisfactory results.
