3.8. Adsorption capacity
Adsorption capacity is an important factor to evaluate the sorbent, because it determines howmuchmodified SDS coated alumina is required for a given solution. The adsorption capacity of the solid phase was studied. The adsorption capacity calculated for Cu, Zn, Fe and Pb were 11.7, 13.6, 15.7 and 13.3 mg g-1, respectively.
