在实际工作中,常常需要对沉积物(岩)中的粘土矿物进行鉴定分析,如果直接采用原样,往往因为其中含有大量的非粘土矿物,使得某些鉴定分析达不到目的,比如作X射线粉晶分析,当样品中含有一定数量的石英时,粘土矿物的衍射线会因石英衍射线的干扰而难于鉴定,因此把非粘土矿物分离出去是非常必要的。目前已有一些完善的 In practice, it is often necessary to identify and analyze clay minerals in sediment (rock). If the original sample is used directly, often the identification analysis can not be achieved because it contains a large amount of non-clay minerals, such as X-ray When the sample contains a certain amount of quartz, the diffraction lines of clay minerals are difficult to identify due to the interference of quartz diffraction lines. Therefore, it is very necessary to separate the non-clay minerals. There are already some perfect ones
