探讨了冰晶石样品用盐酸溶解后 ,当以NH3·H2 O提高PH值过程中反应体系的化学行为 ,扼要提出冰晶石样品中铝及氟含量的测定方法。
The chemical behavior of the cryolite samples dissolved in hydrochloric acid was investigated. The chemical behavior of the reaction system during the process of increasing the pH of the cryolite samples with NH 3 · H 2 O was discussed. The determination of aluminum and fluorine in the cryolite samples was briefly described.
