用ICP对氟石的元素分析
The elelmental analysis of zeolites for their major and minor components requires a sample preparation approach that will dissolve a wide variety of elements without volatilization or precipitation losses. The first of the two main approaches taken by the analytical community has been to perform a fusion with a mixture of lithium tetraborate / lithium carbonate followed by dissolution of the fuseate with dilute nitric acid. The second approach is to perform a digestion of the sample with aqua regia followed by dissolution in cold hydrofluoric acid (< 5°C) and chelation of the excess HF with boric acid.
