Abstract:

This study established a method for the determination of nine β-blockers, including atenolol, in cosmetics using magnetic graphene solid-phase extraction coupled with two-dimensional high performance liquid chromatography tandem mass spectrometry. The samples were extracted with acetonitrile solution, and the targets were adsorbed with magnetic graphene as the solid phase extraction adsorbent. The samples were analyzed by two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS), and quantified by the standard curve external standard method. The findings indicate that a dosage of 8 mg of magnetic graphene, in conjunction with an adsorption period of 20 minutes and the utilization of a 5 mL acetonitrile solution as the eluent, can effectively achieve the enrichment and purification of nine β-blockers. The targets exhibit satisfactory linearity across three distinct matrices: aqueous, emulsion, and cream, within the mass concentration ranges of 50-800 ng/mL and 100-1 600 ng/mL, with the correlation coefficients (r) all greater than 0.999 1. The mean recoveries is found to range from 90.32% to 100.11%, 90.26% to 102.22%, and 90.42% to 102.02%, respectively. The method is characterized by high specificity, high sensitivity, and good reproducibility, and is suitable for the determination of nine β-blockers in complex cosmetic systems.
