摘要
膨润土高温崩解、粉碎搅拌、浸泡直溶三种方法制浆 ,用保险粉做还原剂除 Fe3+离子。结果表明 :高温崩解除铁效果较好 ,除铁率达 86 %以上。
The iron ion in bentonite is removed with Na 2S 2O 4 as reductant after the sample is split at high tempreture, crushed and stired, steeped and dissolved. The result shows that: the effect of removing iron with the splitting method is better than other method, the percentage of eliminating iron from bentonite is more than 86%?
