Impact of carrot extract and pomegranate juice on the structure, magnetic properties and Cr3+ ions removal efficiency of eco-friendly CoFe2O4 nanoparticles prepared via self-ignition technique – Egypt
The nanoparticles exhibited high specific surface areas of 498.49 and 538.17 m2/g for the Co-C and Co-P samples, respectively, contributing to an impressive adsorption capacity, with Co-P achieving 100 % Cr3+ removal within 30 min while Co-C achieved 99.6 % Cr3+ removal within 40 min.
These findings suggest that the green-synthesized cobalt ferrite nanoparticles, with their high surface area and mesoporosity, hold significant potential as effective agents for environmental remediation.
ANOVA analysis further underscored the significant influence of adsorbent dosage and contact time on removal efficiency, aligning well with the freindly isotherm model.
