摘要
高铁酸钾是一种新型的强氧化剂,在水处理中不仅可用于杀灭藻类和细菌,氧化降解水中的无机物和有机物,去除水中一些重金属离子,同时可以起到脱色、除臭、絮凝沉降的作用,且具有见效快、无残留毒性和不对水体造成二次污染等突出优点。作者使用次氯酸盐氧化法(湿法)进行高铁酸钾的合成。并利用高铁酸钾的强氧化性对劣质柴油进行脱色和脱臭实验,讨论了酸度、浓度、温度等对高铁酸钾在水溶液中稳定性的影响,得到当w(HNO3)=4.5%,高铁酸钾质量浓度在100 g/L时处理效果最好,而温度则对处理效果影响不显著。
Potassium Ferrate（PF） is a new type of strong oxidant,in water treatment it can be used not only to kill the algae and bacteria, to oxidize and degrade the inorganics and organics, to remov some heavy metal ions, but also it can play a role in bleaching, deodorant, flocculation settlement, which is quick,no residual toxicity and secondary pollution of water body. In this paper,using hypochlorite oxidation method （wet method） , synthesized PF,and using the strong oxidizability,oxidized the low-grade diesel for bleaching and deodorization experiment. Discussed the effects of the acidity,concentration,temperature on the stability of PF in aqueous solution. When the nitric acid content is 4.5%,PF content is 100 g/L,there is the best effect, but temperature effect on the treatment of low-grade diesel is not significant.
