摘要：

Conditions for the deep degradation of phenol using iron-containing compositions based on silicon nitride at ozonization combined with UV irradiation were determined. The catalytic activity of Si-N-Fe compositions under UV irradiation in the presence of oxalic acid was shown to be photoactive ferric-oxalate complex, which is formed in solution. In other words, a combination of heterogeneous and homogeneous catalysis takes place. GC-MS was used to establish degradation products of phenol. Catalytic composites were tested for the phenol-containing waste water treatment at different Tomsk companies.
