In order to simultaneous extraction and determine of p-nonylphenol (NP), p-nonylphenol monoethoxylate (NP1EO) and p-nonylphenol diethoxylate (NP2EO)from sediment samples, the accelerated solvent extraction parameters were optimized in terms of extracting temperature, extracting pressure, extracting cycle and extracting solvent.
为了同时提取和检测沉积物中的雌性激素化合物对壬基苯酚(NP)、对壬基苯酚一乙氧醚(NP1EO)和对壬基苯酚二乙氧醚(NP2EO),对加速溶剂提取体系的各种条件和对壬基苯酚类化合物的硅烷基化反应条件等进行了优化。
