摘要 | We have established an isotope labeling protocol for determining parabens in wastewater, based on a pair of isotope-coded derivatization reagents, by high performance liquid chromatography (LC) and electrospray mass spectrometry (ESI-MS). The pair of reagents used in our work were d(0)-10-methylacridone-2-sulfonyl chloride (d(0)-MASC, light form) and d(3)-10-methylacridone-2-sulfonyl chloride (d(3)-MASC, heavy form). d(0)-MASC and d(3)-MASC could easily derivatize parabens at 55 degrees C for 7.5 min in the mixture of bicarbonate and acetonitrile (1:1 v/v). It is shown that the derivatization offers 1-2 orders of magnitude signal enhancement over underivatized counterparts. The global isotope internal standard technology was employed for quantification analysis with d(3)-MASC-paraben as internal standard for corresponding d(0)-MASC-paraben. In addition, homologous internal standard was simultaneously used to correct derivatization processes. The obtained double internal standard calibration curves for parabens were linear over the range of 1-500 nmol L-1 (r > 0.997). The isotope coded derivatization based quantification method was precise and practical with RSD <= 3.6% and accuracy ranged 96.5 to 104.7%. The proposed method has also been successfully applied to the quantification of parabens in domestic sewage samples with precisions <= 5.2% and recoveries >= 87.9%. Five kinds of paraben including methylparaben, ethylparaben, propylparaben, butylparaben, and benzylparaben were detected in the tested samples. The quantitative results indicated that parabens were at nmol L-1 level or lower, and ethylparaben were the most abundant, followed by methylparaben, propylparaben and butylparaben. It has been demonstrated that the isotope-coded derivatization reagents are useful for accurate quantification of analytes having target functional groups in real samples. (C) 2016 Elsevier B.V.
