Chromatographic separation of monobutyltin (MBT), monophenyltin (MPhT), dibutyltin (DBT), diphenyltin (DPhT), tributyltin (TBT) and triphenyltin (TPhT) was studied using end-capped reversed-phases (RP) and methanol-acetic acid-water or acetronitrile-acetic acid-water mixtures as mobile phases. Several RP columns were evaluated, and the effect of acetic acid, oxalic acid, triethylamine, and organic modifier on peak shape and retention was examined. A method based on gradient elution RPLC and fluorimetric detection is proposed for the determination of DBT, DPhT, TBT and TPhT. The sensitivity of the method makes it suitable for environmental analysis.
采用封端反相(RP)柱,以甲醇 - 乙酸 - 水或乙腈 - 乙酸 - 水混合物作为流动相,研究了一丁基锡(MBT)、一苯基锡(MPhT)、二丁基锡(DBT)、二苯基锡(DPhT)、三丁基锡(TBT)和三苯基锡(TPhT)的色谱分离。对几种反相柱进行了评估,并考察了乙酸、草酸、三乙胺和有机改性剂对峰形和保留的影响。提出了一种基于梯度洗脱反相液相色谱(RPLC)和荧光检测的方法来测定DBT、DPhT、TBT和TPhT。该方法的灵敏度使其适用于环境分析。
