摘要
论述了高铁酸钾这种新型、高效、安全的多功能水处理剂的三种合成方法,指出每种方法的生产机理,以及每种方法中原料的选择对高铁酸钾产率、纯度的影响,并比较了各种方法的优缺点。同时,讨论了高铁酸钾的有关物理和化学性质,指出定性分析高铁酸钾的方法:红外光谱法,定量分析高铁酸钾的方法:亚砷酸钠氧化还原滴定法。最后还指出由于强氧化作用及溶于水产生的Fe(OH)3的絮凝作用,高铁酸钾在供水工程和污水处理中存在着广泛的应用,而且其应用于水处理实验,效果十分显著。
This paper introduces three methods for preparation of potassium ferrate (VI) as a new, efficient and multipurpose water treatment agent, which is a non-toxic one as well. The mechanism of each method and the effect of raw materials on production rate and purity of potassium ferrate (VI) are studied. Merits and faults of each method are also compared. At the same time, in this paper, the chemical and physical characters of potassium ferrate (VI) are discussed. The qualitative analysis of potassium ferrate (VI) used is IR spectrum and the quantitative analysis of potassium ferrate (VI) is oxidation-reduction titration. Because of its oxidation and coagulation effect, the potassium ferrate (VI) is effectively applied in water supply works and waste water treatment.
