Studying role of air bubbles on suspension of hematite particles with three size ranges in plug flow reactor to improve dyes photo degradation compared to conventional packed bed photo reactors

To have a PBR with the same conditions, Fe2O3 NPs with the mean size equal to that of α-Fe2O3 NPs/pectin used in NPFR, was used the Brunauer-Emmett-Teller method.
