英文摘要: Untreated rice husk (RH) was evaluated as solid-phase extraction (SPE) sorbent for Fluoroquinolone antibiotics (FQs). This natural material, made of cellulose, hemicellulose, lignin and silica, and containing various functional groups, i.e., carboxyl, hydroxyl, and amidogen residues, is a potential sorbent material for polar aromatics like FQs. First, the RH capability to adsorb FQ species from water was studied by batch sorption experiments in tap and river waters, and the experimental data, fitted by the Langmuir model, gave adsorption capacities up to 32 mg g−1. Then, RH was tested as column-packed sorbent for pre-concentration of tap and not tampered river waters spiked with six widely employed FQs, i.e., Ciprofloxacin, Danofloxacin, Enrofloxacin, Levofloxacin,...
