壬基酚是一种典型的环境内分泌干扰物和持久性有毒污染物。以往的研究表明，NP在环境沃茨中的平均浓度约为几十到几百ng L（-1），甚至可以达到几十μg L（-1）。采用新型固相萃取元件“Magic Chemisorber”（MC）和高效液相色谱（HPLC），采用荧光检测器（FLD），建立了一种简便、快速、准确的NP检测方法。对影响提取过程的主要参数，包括提取时间、解吸时间、解吸溶剂和重复性进行了优化。该方法的线性范围为10 ~ 200 μg·L ~（-1），相关系数为0.9995，检测限为0.44 μ g·L ~（-1），定量限为1.47 μg·L ~（-1）。与市售的聚二甲基硅氧烷（PDMS）玻璃纤维相比，MC具有更高的容量和回收率，并可重复使用。采用MC-HPLC法测定杭州市区河水中NP的含量，结果表明，杭州市区河水中NP的含量范围为8.54 ± 1.23 μg L（-1）（钱塘江）~ 65.77 ± 3.69 μg L（-1）（铁砂河），与国际上NP重污染地区的水平相近，高于我国渤海湾、黄河和珠江三角洲的水平。NP污染的这种程度可能与浙江省纺织、印刷和造纸工业的快速发展有关。
Nonylphenol (NP) is a representative environmental endocrine-disrupting chemical and persistent toxic pollutant. Previous studies have shown that the average concentration of NP in environmental waters was approximately tens to hundreds of ng L(-1) and it could even reach up to tens of μg L(-1). A simple, fast and accurate method employing a novel solid-phase extraction element named "Magic Chemisorber" (MC) followed by high-performance liquid chromatography (HPLC) using a fluorescence detector (FLD) was used for detecting NP. The most important parameters that affect the extraction process, including extraction time, desorption time, desorption solvent and repeatability, were optimized. The MC-HPLC method showed good linearity with concentrations of NP from 10 to 200 μg L(-1), a correlation coefficient of 0.9995 and the limit of detection (LOD) and limit of quantification (LOQ) of this method was 0.44 and 1.47 μg L(-1), respectively. Compared to commercial polydimethylsiloxane (PDMS) glass fiber, MC had both higher capacity and recovery and it could be used repeatedly. Using the MC-HPLC method we found that the concentration of NP in river water from Hangzhou city ranged from 8.54 ± 1.23 μg L(-1) (Qiantang River) to 65.77 ± 3.69 μg L(-1) (Tiesha River), which was similar to that of international regions heavily polluted with NP and higher than that of Bohai Bay, the Yellow River and the Pearl River Delta in China. This level of NP pollution is possibly related to the rapid development of the textile, printing and paper industries of Zhejiang province.
