    Liquid–liquid extraction - Wikipedia

    An example of an ion exchange extraction would be the extraction of americium by a combination of terpyridine and a carboxylic acid in tert-butyl benzene. In this case D Am = k terpyridine 1 carboxylic acid 3 H+ −3. Another example is the extraction of zinc, cadmium, or lead by a dialkyl phosphinic acid (R 2 PO 2 H) into a nonpolar diluent

  • Zinc Alloys: Properties, Processing and Applications
    Zinc Alloys: Properties, Processing and Applications

    Zinc alloys are produced by mixing pure zinc with other metals in specific ratios. This provides metals with properties suitable for a range of applications, described below. Zinc alloy parts are produced by casting methods which, depending on the mixture of alloying elements, may be via hot chamber die-casting, cold chamber die-casting
