Adsorption and photocatalytic degradation of aromatic organoarsenic compounds in TiO2 suspension

- ROX and p-ASA are readily degraded by UV TiO2 photocatalysis.
- The solution pH has a pronounced influence on adsorption and degradation.
- The product of mineralization of ROX and p-ASA is As(V).
- TiO2 photocatalysis is an attractive process for the remediation of ROX and p-ASA.
