Characterization and Evaluation of Iron Oxide Nanoparticles Prepared Using Hydrogel Template Based on Phosphonate Alginate
Currently, the use of nano-sorbent for the aqueous heavy metals removal is
popular among researchers.
In this study, iron oxide nanoparticles were developed as a promising adsorbent for Cr (VI)
removal from its aqueous solution. Simple template surface method based on phosphonated alginate
biopolymer was employed for the nanoparticles preparation. Different physical characterization tools
such as FT-IR, SEM, TEM, XRD and magnetic properties were applied to investigate the physicochemical
character of the developed nanoparticles. Batch experiments were used to study the applicability
of iron oxide nanoparticles for Cr (VI) removal from aqueous solutions under different preparation
conditions. The effects of initial Cr (VI) concentration, pH, adsorbent dosage, contact time and
temperature on the removal process were also optimized. Results indicate that the removal efficiency
of Cr (VI) increased from 14.44% to 67.85% with increasing iron oxide nanoparticles dosage from
0.025g to 0.3g. Furthermore, the removal percent rose from 39.11% to 56.04% by increasing the environmental
temperature up to 50°C. While it decreased with increasing initial concentration of Cr (VI).
The best results of removal were recorded at pH=2.
Overall, the obtained results indicate that the developed iron oxide nanoparticles could be
effectively used as adsorbents for removal of Cr (VI) from aqueous solutions.
