In situ interface oxidation-adsorption by ferrate (VI)/PMS self-excitation: Unique dual-reaction platform for phenylarsonic acid degradation and immobilization
Separation and Purification Technology(2023)
Abstract
•First report of PAA oxidize by Fe(VI)/PMS and As(V) adsorb by in situ Fe(III) oxides.•The TOC removal efficiency was >45% and the total-As removal efficiency was >95%.•Oxidation of PAA is dominated by non-free radical pathways.•Fe(VI)/PMS could effectively oxidize PAA and remove total-As in authentic waters.
