METHOD FOR EFFICIENTLY PREPARING FERRATE BASED ON NASCENT INTERFACIAL ACTIVITY

摘要

Provided is a method for efficiently preparing ferrate based on nascent interfacial activity. The method is as follows: a. preparing nascent ferric solution; b. adding an oxidising agent to the ferric solution of step a; c. adding alkali solution or alkali particles to the mixed solution of step b, mixing by stirring, and carrying out solid-liquid separation; d. adding a stabilising agent to the liquid separated out in step c, and thus obtaining ferrate solution; The yield is 78-98%. The prepared ferrate solution is stable and can be stored for 3-15 days.
