The Preparation of Loaded Photocatalyst for Advanced Treatment of NH₃-N in Coking Water

Abstract:

Photocatalyst of Fe-Sm-Yb modified TiO₂ loaded on clay brick was prepared for degradation of NH₃-N in coking water. The influence factors of NH₃-N degradation rates were discussed by single factor experiment and orthogonal experiment. The optimum process conditions of photocatalytic degradation NH₃-N in coking water were confirmed. The results show that NH₃-N degradation rates 82.23% were highest in the conditions of pH 6.5, photocatalyst charge of 1.4 g, illumination for 6h, reaction at 55°C, calcination at 500°C.
