研究了海泡石的组成与离子交换能力之间的关系。通过镁离子酸溶解动力学及XRD和IR研究发现,海泡石的镁具有两种不同的存在形式,Al~(3+)取代部分Si~(4+)进入晶格造成正电荷空位,是影响离子交换作用的主要因素。
The relationship between the composition of the sepiolite and the ion exchange capacity was investigated. According to the dissolution kinetics of magnesium ion and the XRD and IR studies, it is found that there are two different forms of magnesium in the sepiolite. Al ~ (3 +) substitutes part of Si ~ (4+) into the lattice to create a positive charge vacancy The main factors that affect ion exchange.
