Analysis of the Degradation Mechanism of AB1 by GPTMS/TiO2 Composite Catalyst
The printing and dyeing wastewater generated during the dye production process poses significant harm to the environment or human health,and Acid Black 1(AB1)is one of the main harmful substances.In order to improve the treatment efficiency of AB1 in printing and dyeing wastewater,a new type of composite material was proposed as a degradation catalyst for AB1 in printing and dyeing wastewater.The catalyst is mainly composed of TPNC and nano TiO2,with CPTMS as the linking agent.The results showed that when TiO2 was used as a catalyst,after 90 minutes of light catalysis,there was still 63.8％AB1 in the solution.When TNPC-GPTMS/TiO2 with a mass fraction of 0.004％was used as a catalyst,after 90 minutes of light catalysis,AB1 in the solution had been completely degraded and the solution had completed decolorization.The new catalytic material proposed in the study can effectively improve the processing speed of AB1 in printing and dyeing wastewater.
