Antimony Traces Water Monitoring Using Surfactant Sensitized Solid Phase Extraction and Solid Surface Fluorescence

Antimony (Sb) is a nonessential metal to life and is currently considered an emerging contaminant due to its increasing presence in the environment and its toxic effects on humans, plants, and animals.Human activities such as mining, smelting, and burning of fossil fuels, along with the minerals erosion and waste, release antimony into soil and water, posing a serious threat to ecosystems and public health.The objective of this study was to evaluate trace levels of Sb(III) in water samples from the northern and central regions of Argentina using a novel methodology.Sb(III) was complexed with the fluorophore 1,4dihydroxy-9,10-anthraquinone (quinizarin, QZ) followed by solid-phase extraction using filter paper pretreated with hexadecyltrimethylammonium bromide (HTAB).The analyte was subsequently quantified by solid surface fluo-How to cite this paper: Talio, M.
