| 摘 要： | 以钢铁盐酸酸洗废液为原料，亚硝酸钠为催化剂，氧气为氧化剂，在填料塔中催化氧化制备三氯化铁。考察了反应温度、催化剂加入量和添加方式、循环流量等对制备三氯化铁的影响。实验结果表明，在优化的工艺条件为料液预热温度为60 ℃、催化剂加入量为钢铁盐酸酸洗废液总质量的0.30%、料液循环流量6.0 m3/h的条件下，反应80~120 min，酸洗废液中的Fe2+完全氧化为Fe3+。

| Abstract: | FeCl3 was prepared by catalytic oxidation in a packed column using steel pickling waste liquor as raw material，sodium nitrite as catalyst，oxygen as oxidant. The effects of reaction temperature，catalyst dosage and adding method，and circulation flow rate on FeCl3 preparation were investigated. The experimental results show that under the conditions of feed solution preheating temperature 60 ℃，catalyst dosage 0.3% of steel pickling waste liquor mass，feed solution circulation flow rate 6.0 m3/h and reaction time 80-120 min，Fe2+ in steel pickling waste liquor can be oxidized to Fe3+ completly. |
