EJMP&EP -
Cd(II), and Fe(III) ions were studied using Rhizopus arrhizus. As the multicomponent Langmuir model was able to predict the two ternary subsystems of these metal ions satisfactorily, it was further applied in describing the behavior of the quaternary metal systems. To present a summary of the effect of one metal on the uptake ...

ION EXCHANGE CHEMISTRY, CHELATE RESINS
As solutions of metal ions such as Magnesium (Mg), Calcium ... metal is exchanged for sodium ions. The capacity of the columns is about 1.8 pounds of metal per cubic foot of resin depending on the competing ions passing through with the metal. 3. When a column is saturated with a metal, "breakthrough" occurs. This results in a greatly increased passage of metal ions ...
