摘要
在FeSO4母液中,以碱比n=0.8,加入多种不同沉淀剂分别合成多个FeOOH样品;采用相同的沉淀剂,两种亚铁盐,即不同的阴离子环境合成多个样品,并对这些样品进行了晶型、形貌、比表面积、脱硫活性等表征,结果显示由NH4HCO3沉淀的纺锤形纳米FeOOH具有很高的脱硫活性.
In the origin liquid FeSQ （ basicity ratio n = 0. 8 ）, by adding four kinds of different precipitants, synthesized four FeOOH samples separately. Using the same precipitant, different types of anions, synthesized two samples. For all these samples, described their crystalline phases, shapes, BET surface area, desulfurization activity and etc. The result shows that spindle-like Nanometre FeOOH, prepared by NH4HCO3 sedimentation, has the highest desulfurization activity.
