A method for quantitative evaluation of pentachlorophenol (PCP) in sawdust has been developed. Pentachlorophenol is extracted from the solid matrix with 0.5 M sodium hydroxide and preconcentration was carried out using quinolin-8-ol immobilized on controlled pore glass. Determination was carried out by using liquid chromatography with detection at 240 nm. Recoveries were between 84 and 97% at 1-3 microg/g.
已开发出一种定量评估木屑中五氯苯酚（PCP）的方法。用0.5 M氢氧化钠从固体基质中提取五氯苯酚，并使用固定在可控孔径玻璃上的8-羟基喹啉进行预浓缩。采用液相色谱法在240 nm波长处进行检测。在1 - 3微克/克的添加水平下，回收率在84%至97%之间。
