Analytical Solvent Extraction of Molybenum Using Acetylacetone

Simultaneous Spectrophotometric Determination of Cobalt and Nickel with 2,3-Quinoxalinedithiol.

“…Steinbach and Freiser ( 14), using acetylacetone as both a solvent and a reagent, found that the efficiency of the copper extraction is 85 to 87% over the pH range 2 to 5, wfiiereas the percentage extraction of iron from sulfuric acid solutions varying in pH from 0.3 to 2.0 is 10 to 99.9%, respectively (9).…”

Spectrophotometric method for hydrofluoric acid in stainless steel pickling baths

“…It is obvious, however, that neither chromium or nickel appear to interfere either by dissociation of their fluoride complexes or the formation of colors with acetylacetone. The acetylacetonates of most metals form either weak colors or, like chromium, require heating for color formation (8,9).…”

Neutron Activation and Radiochemical Determination of the Molybdenum, Chromium, and Iron Content of Individual Stainless Steel Microspheres.

“…The quest for a simple, rapid, highly selective method for the determination of fluoride ion has produced a voluminous literature. A comprehensive review of the subject has been published recently (8).…”
