摘要：

This work presents experimental results obtained in the process of Cd(2+) removal from model solutions using batch (magnetic stirring) and fixed bed procedures. As adsorbent we used a mixture consisting of bentonite and baker's yeast (2, 4, 6 and 8 g in 1:0, 3:1, 1:1, 1:3 and 0:1 ratios), immobilized in calcium alginate. Adsorption capacities were calculated, and breakthrough curves were plotted in order to describe the influence of various working conditions (adsorbent type and ratio, initial cadmium concentration) over the process efficiency. Adsorption capacities up to 12.74 mg Cd(2+)/g adsorbent were calculated.
