文摘

Complexation-ultrafiltration and photocatalysis for As removal were offline coupled. pH and polymer/As ratio, giving 100% As(V) complexation, were determined. As speciation was performed by using the CP-UF process for analytical purposes. 90% As(III) oxidation was obtained in 10 min under UV by using TiO2, O2 and pH 9. A scheme of online coupling and some criteria to run the CP-UF step are reported.
