Enhancing acid orange II degradation in ozonation processes with CaFeO nanoparticles as a heterogeneous catalyst
This study used CaFe 2 O 4 nanoparticles as a catalyst for ozonation processes to degrade Acid Orange II (AOII) in aqueous solution. The study compared heterogeneous catalytic ozonation (CaFe 2 O 4 /O 3 ) with ozone treatment alone (O 3 ) at different pH values (3-11), catalyst dosages (0.25-2.0 g L...

nanoparticles as a catalyst for ozonation processes to degrade Acid Orange II (AOII) in aqueous solution. The study compared heterogeneous catalytic ozonation (CaFe

) with ozone treatment alone (O
3
) at different pH values (3-11), catalyst dosages (0.25-2.0 g L
−1
), and initial AOII concentrations (100-500 mg L
−1
). The O
3
alone and CaFe
2
O

/O
3
systems nearly completely removed AOII's color. In the first 5 min, O
3
alone had a color removal efficiency of 75.66%, rising to 92% in 10 min, whereas the CaFe
2
O
4
/O
3
system had 81.49%, 94%, and 98% after 5, 10, and 20 min, respectively. The O
3
and CaFe
2
O
4
/O
3
systems degrade TOC most efficiently at pH 9 and better with 1.0 g per L CaFe
2
O
4
. TOC removal effectiveness reduced from 85% to 62% when the initial AOII concentration increased from 100 to 500 mg L
−1
. The study of degradation kinetics reveals a pseudo-first-order reaction mechanism significantly as the solution pH increased from 3 to 9. Compared to the O
3
alone system, the CaFe
2
O
4
/O
3
system has higher
k
values. At pH 9, the
k
value for the CaFe
2
O
4
/O
3
system is 1.83 times higher than that of the O
3
alone system. Moreover, increasing AOII concentration from 100 mg L
−1
to 500 mg L
1
subsequently caused a decline in the
k
values. The experimental data match pseudo-first-order kinetics, as shown by
R
2
values of 0.95-0.99. AOII degradation involves absorption, ozone activation, and reactive species production based on the existence of CaO and FeO in the CaFe
2
O
4
nanocatalyst. This catalyst can be effectively recycled multiple times.
