A method for the quail-quantitative evaluation of pentachlorophenol (PCP) in solid matrixes has been developed. The procedure is based on solid-liquid extraction of solid samples (leather or wood), followed by purification on a cyanopropyl column and determination of the preservative by second derivative UV spectroscopy considering the PCP A peak-through value (304-297 nm). The method allows rapid PCP determination in the concentration range 1-40 micrograms/mL; any matrix interference is avoided by the purification step and recoveries of the preservative were 99.12% (RSD% 0.13) for the leather matrix and 98.03 (RSD% 0.17) for the wood matrix.
已开发出一种对固体基质中五氯苯酚（PCP）进行定量评估的方法。该程序基于对固体样品（皮革或木材）进行固液萃取，然后在氰丙基柱上进行净化，并通过二阶导数紫外光谱法测定防腐剂，该方法考虑了PCP A峰通值（304 - 297纳米）。该方法能够在1 - 40微克/毫升的浓度范围内快速测定PCP；净化步骤避免了任何基质干扰，皮革基质中防腐剂的回收率为99.12%（相对标准偏差0.13%），木材基质中为98.03%（相对标准偏差0.17%）。
