Iran makes nanoabsorbent for determining sulfonamide


Researchers of Islamic Azad University’s Shahr-e Rey Branch have produced a nanoabsorbent for determining sulfonamide in chicken by using a magnetic polymer.

Mohammad Karimi and Ezzatollah Najafi were researchers of the project.
Sulfonamides are fed to chickens to increase growth but its excessive use in chicken feed may lead to gastrointestinal problems, backache, headache, vertigo, diarrhea, anorexia, nausea and jaundice.
Fe3O4 magnetic nanoparticles were synthesized by a molecularly imprinted polymer for easy extraction and determination of sulfonamides in the samples of chicken meat.
The magnetic nanoparticles were characterized by X-ray diffraction pattern, thermal analysis and scanning of electron micrograph.
The template was removed by methanol elution. Sulfonamide separation was performed by liquid chromatography–UV.
Results of the study indicated that the nanoabsorbent is useful in quick determination of sulfonamides in chicken meat.
Sulfonamides (sulfa drugs) are derived from sulfanilamide, a sulfur-containing chemical.
