40 "chromate method" for separating earths. vickery. 



Summary 



1. Each precipitation occurring in the chromate process 

 for the separation of the alkaline earths has been quantitatively 

 investigated. 



2. The chromate process has been found not to effect 

 an exact separation of the three metals. 



3. An improvement has been suggested by which the 

 separation is practically complete, and a procedure for- 

 mulated. 



4. The limit of detectability for each metal by this 

 procedure has been determined.
