Based on the porous structure of the Zeolite type Linde A, it was modified by the
dimercaptothiadiazole lead compound (PbDMT). The detection of these changes on
zeolite was characterization by using the techniques (FT-IR, XRD, AFM and SEM).
The study of adsorption of the Congo red dye from its aqueous solutions on both
surfaces adsorbents before and after modification (Zeolite , Zeolite - PbDMT) through
Several factors (contact time, temperature and concentration of Congo red dye (CR).
The kinetic results of the Congo red adsorption process showed that the equilibrium
time at which the maximum value of adsorption of the Congo red dye was for each of
the two surfaces adsorbents respectively. More than one kinetic model was applied to
the experiments values. The results showed fit applied on pseudo second order equation
for both surfaces adsorbents studied
