摘要
将ＫＭｎＯ４于２００～１０００℃范围内的不同温度下恒温分解，制得Ｋ４Ｍｎ７Ｏ１６·ｎＨ２Ｏ（ｎ≈３）、ＫＭｎ８Ｏ１６等不溶性锰酸盐．实验证明，这些锰酸盐对铁离子均有吸附作用，其中吸附量最大的吸附剂是在５５０℃下制备的ＫＭｎ８Ｏ１６在吸附除铁过程中存在着离子交换作用．
It is shown with experimental data that KMnO4 can be decomposed into different products at different temperature between 200℃ and 1000℃. The insoluble products, such as K4Mn7O16·nH2O(n3) KMn8O16 etc., have different adsorption capacity to iron ions and KMn8O16 prepared at 550℃ has the maximun absorption. In the adsorption, ion exchange occurs.
