Solid phase extraction and determination of Sulfathiazole by Spent coffee ground as greenadsorbent

In this study, Sulfathiazole was preconcentrated, extracted by solid phase extraction (SPE), anddetermined by using UV-Vis spectrophotometry. Coffee residues were used as green bio-adsorbent. The mainfactors affected the SPE investigated and optimized, such as the adsorbed amount, and sample pH value. Underthe optimal experimental conditions, the detection limit and the limit of quantification were studied
