Kaewchuay, Netnapit published the artcileSimultaneous determination of pyridine-triphenylborane anti-fouling agent and its degradation products in paint-waste samples using capillary zone electrophoresis with field-amplified sample injection, COA of Formula: C23H20BN, the publication is Analytical Sciences (2012), 28(12), 1191-1196, database is CAplus and MEDLINE.
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, resp., 0.85, 0.88, 44, and 28 μg/L. The RSDs (n =4) for the analytes listed above were 6.2-14, 5.9-10, and 0.49-0.62% for the peak area, peak height, and migration time, resp. The compounds were extracted from paint-waste samples collected from shipyards using a silica-gel column. The extract was dissolved with acetonitrile containing 1% (volume/volume) pyridine. The samples were then analyzed using CZE, revealing resp. concentrations of 0.076-0.53, 0.015-0.36, 1.7-22, and 1.2-13 μg/g. 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.
