We proposed a capillary zone electrophoresis (CZE) procedure using field-amplified sample injection (FASI) for the simultaneous determination of pyridine-triphenylborane (PTPB) and its degradation products: diphenylborinic acid (DPB), phenylboronic acid (MPB), and phenol. The LODs for PTPB, DPB, MPB, and phenol were, respectively, 0.85, 0.88, 44, and 28 μg L(-1). The RSDs (n = 4) for the analytes listed above were in respective ranges of 6.2 - 14, 5.9 - 10, and 0.49 - 0.62% for the peak area, peak height, and migration time. The compounds were extracted from paint-waste samples collected from shipyards using a siliga-gel column. The extract was dissolved with acetonitrile containing 1% (v/v) pyridine. The samples were then analyzed using CZE, revealing respective concentrations of 0.076 - 0.53, 0.015 - 0.36, 1.7 - 22, and 1.2 - 13 μg g(-1). The proposed FASI-CZE method is a simple and promising procedure that is expected to be useful for the determination of PTPB and its degradation products in paint wastes.
我们提出了一种采用场放大进样（FASI）的毛细管区带电泳（CZE）方法，用于同时测定吡啶三苯基硼烷（PTPB）及其降解产物：二苯基硼酸（DPB）、苯基硼酸（MPB）和苯酚。PTPB、DPB、MPB和苯酚的检测限分别为0.85、0.88、44和28μg L⁻¹。上述分析物的相对标准偏差（n = 4），峰面积、峰高和迁移时间的范围分别为6.2 - 14%、5.9 - 10%和0.49 - 0.62%。使用硅胶柱从造船厂收集的油漆废料样品中提取这些化合物。提取物用含有1%（v/v）吡啶的乙腈溶解。然后使用CZE对样品进行分析，结果显示其各自的浓度为0.076 - 0.53、0.015 - 0.36、1.7 - 22和1.2 - 13μg g⁻¹。所提出的FASI - CZE方法是一种简单且有前景的方法，有望用于测定油漆废料中的PTPB及其降解产物。
