Efficiency of catalytic systems

Capability of B-N-Fe composition samples to remove oxalic acid (OA) from water was investigated [24] and it was established (Table 7.5) that sorption of OA depends on surface and porosity properties of the material used and does not exceed 40%. H2C2O4 decomposition degree under UV in presence of each sample is rather high (80-90%). Addition of HgOg (photo-Fenton system) does not affect the catalytic activity of composites. Adsorption and catalytic activity of materials were investigated used by XRD and IR methods. Formation of photoactive ferric-oxalate complexes explains efficiency of catalytic systems (Equations 7.11-7.15).
