摘要:
在超声波场条件下,以电子工业产生的铜氨废液为原料、水合肼为还原剂、聚乙烯吡咯烷酮为表面活性剂还原制备纳米铜粉。研究了该体系下温度、pH值、表面活性剂添加量和超声波场等因素对制备纳米铜粉的形貌和粒径的影响。通过试验探索得到最佳反应温度为:72 ℃;pH值:9.0~10.0;表面活性剂添加量为:0.2 mol·L-1。此外,在超声波场条件下制备的产物粒径小于无超声波场条件下的产物。制备的产物通过X射线衍射(XRD)、扫描电镜(SEM)表征,结果表明产物为纯度很高的铜粉,粒径达到纳米级别,形貌呈球形。在最佳工艺条件下,废液中铜离子的转化率达到97%以上,试验反应产物为氮气,没有引入新的金属离子,反应前后体系成份未变,可以浓缩后返回车间做铜板碱性蚀刻液使用,实现了绿色环保要求
Abstract:
The copper nanoparticles were prepared in ultrasonic field by using the copperammonia waste water as the starting material and hydrazine hydrate as reducing agent, as well as polyvinyl pyrrolidone as surfactant. In this paper, the influence of temperature, pH value and the amount of surfactant on particle size and morphology of copper nanoparticles were studied. The optimum reaction condition was the temperature about 72 ℃, pH among 9.0~10.0 and the amount of surfactant 0.2 mol·L-1. Meanwhile, the copper nanoparticles in ultrasonic field appeared smaller than usual. The prepared copper nanoparticles were characterized by XRD and SEM. The results showed that the product was pure copper powder, which had spherical morphology with nanoscale size. Under the optimum technological condition, the conversion ratio of copper ion in copperammonia waste water was more than 97% and the reaction product was nitrogen. After reaction, the reaction system composition had no variation compared with original liquid, due to no new metal ions being added during the reaction. The waste water after reaction can be returned to workshop as new alkaline etching liquor and green environmental protection realizes.
