Description:
Herein, we describe synthesis of novel palladium, copper, cobalt and vanadium ferrites. The ferrites were synthesized by combustion method using polyvinyl alcohol. The particles phases were confirmed using X-ray diffraction and sizes were determined using particle size analyzer. The synthesized ferrites were used to degrade or remove different dyes such as methylene blue and bromothymol blue. The BET surface area increased with increasing iron content (9-24 m2/g) for CuFe2O4 samples. The BET surface area was lower for PdFe2O4 samples as compared to CuFe2O4. CoFe2O4 had the highest surface area (42 m2/g). The SEM images indicated that Cu and Pd ferrites had flake kind of structures, whereas the CoFe2O4 ferrites had distinctive surface morphology with very small spherical nanoparticles arrayed on a large flake kind of structures. The TEM images showed that the synthesized particles were in the range of nanoscale. Studies looking at the degradation of emerging contaminates such as tetracyclines, progesterone, and octylphenol are underway.
