Binding of Fluoroquinolone Carboxylic Acid Derivatives to Clay Minerals

Nowara, Adrian, Burhenne, Jürgen, Spiteller, Michael·1997·Journal of Agricultural and Food Chemistry

Abstract

Large quantities of fluoroquinolone carboxylic acid (FQCA) derivatives are applied as antibacterial agents in large-scale animal husbandry. Important quantities are transported to agricultural areas by means of liquid manure. The binding of FQCA derivatives to clay minerals and their sorption by five soils from different geographic areas were investigated. Sorption was studied in batch experiments using radioactive labeled enrofloxacin (Baytril), decarboxylated enrofloxacin, ciprofloxacin (Cyprobay), levofloxacin (Oxaldin), and a fluorochloroquinolone carboxylic acid derivative. More than 90% ( K D = 260−5612) of the applied enrofloxacin adsorbed on the different soils. The other chemicals showed a similar adsorption ( K D = 285−496) on a German soil except the decarboxylated enrofloxacin ( K D = 7.7). At clay minerals enrofloxacin was adsorbed >98%. X-ray diffraction analysis showed that the adsorption at the clay mineral montmorillonite occurred between the layers, resulting in an expansion of the spacing. Microcalorimetric and infrared measurements confirmed an electrostatic interaction between the adsorbed chemical and the adsorbent. Keywords: Adsorption; clay mineral; enrofloxacin; fluoroquinolone carboxylic acid derivatives; Coulombic interactions; soil clays

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
