摘要
固阳膨润土是一种蒙脱石含量高(主矿层>90%)的钙基膨润土。蒙脱石为切托型,Fe低、Mg高,阳离子交换容量大。八面体晶层中Mg2+→Al3+的置换量达26.9%~29%,因此具有良好的活化性能。适宜的活化酸度为10%(HCl)。最高脱色力302.6。
Guyang bentonite is a kind of the Ca bace bentonite containing montmorillonite more than 90% in main ore bed.The montmorillonite is Cheto type with lower Fe and higher Mg and C E C.The replacement of Mg 2+ →Al 3+ in the octahedron is up to 26.9% ̄29%,and therefore its activation is excellent.The saitably activated acidity is 10% HCl.The highest decolorant capacity of the activated bentonite is 302.6.Its activation may be increased with sodium salt for activator.
