A new selective method was developed for the separation and preconcentration of Cd (II)
ions based on its complex formation with Xylenol orange loaded on activated carbon as a
solid support in a mini-column. The preconcentrated ions were eluted by passing 5.0 mL 0.5
mol L-1 HNO3 solution through the solid support and then the Cd (II) contents was
measured by flame atomic absorption spectrometry. Conditions for preparation of the
modified activated carbon, pH and flow variables were studied, as well as, the effect of ...
