- Abstract
- PEEK-WC nanostructured capsules were prepared by the phase inversion technique and used as support
for the coating of a manganese dioxide layer. The coating was done by a chemical treatment of the capsules
followed by a thermal one. The presence of the MnO2 layer was confirmed by scanning electron
microscopy (SEM), back scattering electron (BSE), energy dispersive X-ray (EDX) and X-ray diffraction
(XRD) analysis. The produced capsules were, then, tested for As(III) oxidation in batch. The experiments
consisted in treating 165 ml of As(III) solution with 1 g of coated capsules at fixed temperature (15 oC)
and pH (5.7-5.8). In particular, the efficiency of the system was investigated for different As(III) concentrations (0.1, 0.3, 0.7 and 1 ppm). For feeds at lower As(III) content (0.1-0.3 ppm), tests lasted for 8 h,
while prolonged runs (up to 48 h) were carried out on more concentrated solutions (0.7 and 1 ppm). The
produced capsules were able to oxidize As(III) into As(V) leading to complete conversion after 3 and 4 h
for feed concentrations of 0.1 and 0.3 ppm, respectively. (literal)
