Abstract:

Cadmium adsorption on gibbsite was examined as a function of pH, background electrolyte concentration, and adsorbate loading. The adsorption data was quantified by charge distribution multi-site ion complexation (CD MUSIC) model using reaction stoichiometry given; 2(>AlOH−1/2)+Cd2+=(>AlOH)2xCdy; log K=6.727. The charge distribution factor, f is treated as an adjustable parameter in model fitting yielding x=1.2 valence units (vu) and y=0.8 vu.
