The effect of a two-pot postsynthetic modification of MOF with a modified LDH on the adsorption of Pb ions was investigated. Co-MOF was postsynthetically modified with an amino- silane substituted LDH and applied for the adsorption of Pb from aqueous solution. Synthetic and postsynthetic products were characterized by FTIR, PXRD and TGA/DTA. Blueshifts and redshifts of existing FT-IR bands in the PSM product in relation to that of the precursors confirmed the modification. PSM product was stable at temperatures up to 400ºC after a slight loss of surface water at low temperatures Adsorption capacity with respect to time at equilibrium was 34.58 mg/g, representing 87% of adsorbate uptake by the PSM Co-MOF. Equilibrium sorption data was better correlated by the Temkin model with a heat of sorption at 33.72 J/mol.  Kinetic modelling was most favoured by the pseudo second order, and diffusion by film diffusion model.
