中文摘要:
      在NaOH溶液中,以Fe(NO3)3·9H2O和Cu(NO3)2·3H2O为前驱体,采用水热法制备了负载型的纳米CuFe2O4/Ac,采用XRD和TEM对所得样品的结构和形貌进行了表征.分别考察了催化剂类型、用量,微波辐射时间、微波辐射功率对RhB降解效果的影响. 结果表明:CuFe2O4/Ac纳米颗粒能够有效促进罗丹明B(RhB)的微波降解,对于38.3 mg/L的RhB,微波辐射时间1 min,微波功率400 W,催化剂CuFe2O4/Ac用量为0.5 g时,罗丹明B的降解率可达到99%,TOC去除率为89%.
英文摘要:
      CuFe2O4/Ac nanoparticles were prepared by hydrothermal method in sodium hydroxide solution with copper and iron nitrates as precursors. The structure and shape of the CuFe2O4/Ac nanoparticles were characterized by XRD and TEM. The effect of catalyst type, load, microwave irradiation time and power on the degradation of RhB was also investigated. The results showed that the degradation of RhB under microwave irradiation could be greatly enhanced over CuFe2O4/Ac nanoparticles. The added RhB (38.3 mg/L) could be removed with a rate of 99% in 1 min by using 0.5 g CuFe2O4/Ac nanoparticles under microwave power 400 W, and the TOC removal rate was 89%.
