- 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
