  • 摘要: 本实验利用溶剂热法合成了铋掺杂氧化铟催化剂,利用XRD、EDS和SEM对催化剂的结构和形貌进行了表征.研究表明,铋离子已经掺杂进氧化铟的晶格中.掺杂后的催化剂粒径为纳米级,且具有良好的球形形貌.本文以偶氮染料直接大红废水为目标降解物,分别考察了不同催化剂对该染料废水的降解性能以及铋掺杂氧化铟催化剂的投加量、染料的浓度、溶液的pH、超声频率和超声功率对该染料的降解性能.在本实验条件下,催化剂投加量为7.5 mg、染料浓度为10 mg·L-1、pH值为6、超声频率为45 kHz、功率为100 W时,对染料废水的去除效果最优,总去除率可达83.7%,比空白实验的去除率提高将近5倍.
    Abstract: In this study, a novel catalyst, bismuth doped indium oxide, was synthesized via a solvothermal method, and its structure and morphology were characterized by XRD, EDS and SEM. The results indicate that bismuth ions were well doped into the lattice of indium oxide, and the particle size of catalyst with good spherical shape was on the nanoscale. In the experiment, Congo red was applied to validate the degradation property of different catalysts. The effects of the operating parameters, such as the dosage of bismuth doped indium oxide, initial dye concentration, pH value, medium ultrasonic frequency and ultrasonic power on the degradation were evaluated. Under the experimental condition, the removal rate was up to 83.71% with the optimum parameters, i.e. a catalyst dosage of 7.5 mg, an initial concentration of 10 mg·L-1, an ultrasonic frequency of 45 kHz and an ultrasonic power of 100 W in just 60 minutes. The total removal rate increased nearly five times than the blank experiment.
