Separation of Toxic Organotin Compounds from Aqueous Solution by Adsorption

The adsorption characteristics of organotin compound (tributyltin oxide) are established on activated carbons, polymeric adsorbent, and synthetic carbonaceous adsorbents. Maximum adsorptive capacity is obtained with activated carbon containing high percentage of macropores (100–500 Å). For this carbon the adsorptive capacity (g organotin adsorbed/g of adsorbent) at breakpoint is 0.30 and the capacity at exhaustion (with 30 mg/L organotin solution) is 0.50.
