Description
本发明涉及 化合物的制备方法 。
目前,制备高铁酸盐的基本方法有三种:(l)湿法氧化法;(2)电解法;(3)高温过氧化法(干法)。但是这些方法应用于工业生产均有一定的局限性。次氯酸盐法方法成熟,产率及纯度好,但是操作时要求控制温度接近零摄氏度,程序复杂,容易引入其它污染物;电解法操作简单,原材料消耗少,但电力消耗大,副产物多,影响因素多,产率低;高温过氧化物法纯度和产率也较高,但操作需要较高温度,存在爆炸的危险。
由于高铁酸盐处理具有氧化、吸附、共沉、消毒、杀菌、除藻等多功能的净水效能,是工业废水及饮用水理想的处理剂。目前限制其大规模应用的主要是目前报道的各种制备方法合成过程复杂、高铁酸盐产率低,商业化生产投资大、产品成本过高。
