At elevated humidities mixtures of soluble and insoluble material are often readily discernible in single particles.

在大湿度时,可溶的和不可溶的物质的混合物很容易在单个粒子中辨认出来.

F-1 and Cl-1 formed insoluble material can be removed. K+ and Na+ formed the jarosite slag can be removed while removing ferrous ion.

氟氯也可以形成不溶物给除去，K+、Na+也可以由黄钾铁矾除去铁的同时形成黄钾铁矾渣而排出系统。
