Abstract: The stable FeO nanofluid was prepared in this work. The ammonia bubble absorption experiments for FeO nanofluid-based solution and water-based solution were carried out and compared under the two different conditions of constant flow flux and constant inlet pressure of ammonia gas，respectively. The results showed that the absorption effect of ammonia was enhanced by the prepared FeO nanofluid. At a constant flow rate of ammonia gas，the enhanced absorption effect was not observed until several minutes later from the beginning of the absorption process. Under the condition of constant inlet pressure，the absorption effect was observed immediately at the very beginning of the absorption process. The possible reasons for the above enhancement phenomenon were also given.

摘要： 配制了性能稳定的FeO纳米流体，并利用氨水鼓泡吸收实验装置分别在氨气定流量和定入口压力条件下，对以水和FeO纳米流体为基液的溶液进行了氨水鼓泡吸收的对比实验。实验发现，纳米流体对氨水鼓泡吸收具有一定的强化效果：在氨气定流量条件下，吸收过程开始一段时间后才表现出强化吸收效果；在氨气定入口压力条件下，吸收过程一开始就表现出了强化吸收效果。分析了上述强化吸收现象可能的原因。
