Ciprofloxacin (CIP)-soil sorption interactions by surface complexation (via -COOH group) and cation exchange (-NH3+ group) were estimated by use of the structurally related probe compounds flumequine (FQ) (-COOH) and phenylpiperazine (PP) (-NH3+). Comparison of CIP and FQ sorption by surface complexation on goethite indicated a 0.7 times lower driving force for sorption, K(xs), for CIP than for FQ, with a model that assumed functional group interactions were enhanced by the hydrophobicity of… CONTINUE READING
