摘要
报道了高铁酸钾的合成。它易溶于水，标准电极电位为２２Ｖ，氧化杀菌能力大于ＫＭｎＯ４和次氯酸盐，无二次污染，适用ｐＨ宽，当水源中大肠杆菌为１８４×１０５～２８３×１０５个／Ｌ时，用５～６ｍｇ／Ｌ此溶液处理３０ｍｉｎ，杀灭率为９９９５％～９９９９％，可达一般生活用水标准。
This paper reports the synthesis of K 2FeO 4 crystal.It is easily dissolved in water.Its standard electrode potential is 2.2V,its oxidizing and bactericidal capability exceeds KMnO 4 and hypochlorite.It hasn't the second pollution.The applicable pH area is wide.When large intestine bacilli in the water are 1.84×10 5～2 83×10 5/L,we can use the solution 5～6mg/L.After thirty minutes,bactericidal ratio is 99.95%～ 99.99% .It can satisfy the water supply standard.
