采用硼氢化钠为还原剂液相还原法制备纳米Ni-B粉,分析考察了其催化分解特性,研究酸度和温度等因素对催化反应的影响,并对模拟含肼废水进行降解实验。结果表明,肼的催化分解产生氮气和氨气,温度控制在60℃,pH值为12,经5h反应,肼浓度为1~2g/L的废水可完全降解。 Nano-Ni-B powder was prepared by liquid-phase reduction using sodium borohydride as reductant. The catalytic decomposition was investigated and the influence of acidity and temperature on the catalytic reaction was studied. The degradation experiment of simulated hydrazine-containing wastewater was carried out. The results showed that the catalytic decomposition of hydrazine produced nitrogen and ammonia gas. The temperature was controlled at 60 ℃ and the pH value was 12. After 5h reaction, the wastewater with hydrazine concentration of 1 ~ 2g / L could be completely degraded.
