Determination of metformin and triclosan in sewage sludge using Liquid chromatography-mass spectrometry (LC-MS)

Pharmaceuticals and personal care products (PPCPs) are generally neither totally removed by sewage treatment nor completely destroyed in the environment. Metformin (MET) triclosan (TRI) two compounds PPCPs that have potential to be environmental pollutants. This research aimed determine MET TRI sludge using a liquid chromatograph-mass spectrometer (LCMS-8040) extraction method. The Milli-Q water were also tested at three different concentrations (0.01, 0.02, 0.03 mg L-1). As result, corresponding recoveries of both matrixes ranged from 85.93 116.10 per cent 90.50 116.30 (n = 7, RSD < 10%). Then, limit detection (LOD) quantification (LOQ) for found 0.005 0.01 L-1. amounts samples Ukkadam plant (USTP), Coimbatore, BDL 0.0587 L-1 0.0719 0.1851 L-1, respectively. Consequently, Tamil Nadu Agricultural University (TSTP), 0.0227 0.0393 0.1296 exclusive use highly sensitive LCMS-8040 consumes less time than other analytical methods measuring amount overcoming risk chemical degradation.
