Comparison of solid-phase sorbents for the determination of fluoroquinolone antibiotics in wastewater.
Three different SPE sorbents (weak cation exchange, mixed cation exchange, and hydrophobic-lipophilic balance polymers) were compared in terms of recovery, precision, and the effect of matrix components on analyte response for the determination of fluoroquinolones antibiotics. The influence of ethylenediaminetetraacetic acid disodium salt (Na(2)-EDTA) was as well tested. Two of the sorbents, hydro
