Determination of norfloxacin by sensitized terbium fluorescence in the presence of silver nanoparticles and surfactant micelles

Abstract

Sorbents synthesized based on high-basicity anion exchangers by modifying polyvinyl chloride polymers with polyethylene polyamine (sorbent PPE-1), as well as polyacrylonitrile (sorbents PPF-1 and PPA-1), were used for the selective sorption of copper(II) ions. In the case of polyacrylonitrile modification, the reagent thoron I was immobilized on the surface of the sorbents. Optimal conditions for the immobilization of the reagent on the sorbents and the formation of complexes with copper(II) ions in a static mode were studied. A method for sorption-atomic absorption determination of copper(II) ions in technogenic, waste, and industrial waters was developed.
