Abstract
With the general method of marine salt analysis, alkaline metal sulfates could not be determined, being covered with mother liquors.
When the sample was washed with ether and ethylalcohol, the sulfates remained in the residue, and could then be detemined in single form or as double salts compounded with alkaline earth metal sulfate.
Then, this method was applied to other substances separated in salt making-common salt, bittern salts, and their byproducts.
