PHARMACEUTICAL COMPOUNDS DETERMINATION IN WATER SAMPLES: COMPARISON BETWEEN SOLID PHASE EXTRACTION AND STIR BAR SORPTIVE EXTRACTION

ABSTRACT A variety of organic compounds and their metabolites used in pharmaceutical and personal care products (PPCP´s) are continuously introduced into the environment by domestic or industrial wastewater. Solid phase extraction (polymeric dinivylbenzene cartridge) and stir bar sorptive extraction...
