Preparation and photo-catalytic behavior of conjugated polymers based on paper-making wastewater.
Based on alkaline paper-making wastewater, a polymer catalyst (FQ) was prepared and characterized by FTIR, ESR and element analysis techniques. The results show that the catalyst has conjugated structure and the conjugate degree increases after heat treatment. The catalyst has quite high photo-catalytic activity, which was verified by the fact that the simulated dyeing wastewater containing methylene blue (MB) or acridine orange (AO) can be degraded completely in 20 minutes under natural light using FQ as the photo-catalyst. Therefore, the synthetic dyeing wastewater can be disposed of using the materials coming from paper-making wastewater. It is a very promising method to treat one kind of wastewater with the materials from another kind of wastewater.
