NOTE Further Studies on Soluble Iron in Filter Aids. Allen E. Swisher and C. G. Morris, Sales Service Laboratories, Dicalite/Minerals Division/Grefco, Inc., Torrance, CA 90505. J. Am. Soc. Brew. Chem. 39:0115, 1981.

Studies are reported on the correlation of phthalate-soluble iron with beer-soluble iron for calcined and flux-calcined diatomaceous earth (D.E.) filter aids. Each type of filter aid was found to produce a separate correlation curve. Flux-calcined D. E. exhibited a very good correlation. The correlation was very poor for calcined D.E., however.
