摘要
将共轭高分子聚西弗碱PSB,经适当条件热活化处理后成功地用作染料废水处理催化剂。利用DTA-TG、TEM、FT-IR、UV-Vis、COD等测试技术对样品结构及催化性能进行了表征。结果表明,所得材料在自然光照射及空气氧存在的温和条件下,几分钟内就能使染料亚甲基蓝(MB)几乎完全脱色降解,矿化度达到65.7%,而且所得材料具有很高的稳定性,可被重复使用9次以上。材料共轭性主链结构和C N、C O等极性基团的存在,是其表现优良催化性能的主要影响因素。
After properly heat-activated treatment, a functional polymer PSB （polyschiff base） nanomaterial, PSB-1 - PSB4, was successfully obtained and used as catalyst in water pollution treatment. The samples were determined by means of DTA-TG, TEM, FT-IR and UV-Vis. Results show that under natural light and air conditions, methylene blue （MB） could be almost fully degraded in the presence of PSB within a few minutes, the mineralizing efficiency reached to 65.7%. Furthermore, the catalyst has superior stability and it can be reused for nine runs. The existence of conjugation structure and polar groups such as C=N , C=O was found to be decisive factors for the catalytic property.
