Pdf The Adsorption Of Pb Zn Cu Ni And Cd By Modified L The freundlich model was successful in analysing experimental data of ni and zn ions onto fgcx while that of pb, cu, and cd did not fit the model very well. the k f values decreased in the order of ni (2.13) > zn (2.05) > pb (1.79) > cu (1.7) > cd (1.46 mmol g); the n values indicated favourable adsorption for the considered metal ions. Study on the adsorption of pb, zn, cu, ni, and cd by modified ligand in a single component aqueous solution: equilibrium, kinetic, thermodynamic, and desorpt. Atomic adsorption spectrophotometer (varian spectraa 10) was applied in determining the amount of metal ions adsorbed. 2.2. adsorbate preparation. the stock solutions of cu2 , cd2 ,zn2 ,pb2 ,andni2 were obtained by separately preparing a calculated mass of cuso4⋅5h2 o, cdcl2⋅h2 o, zn(no3)2⋅6h2 o, pb(no3)2, and niso4⋅6h2 o. this stock. Results showed that the adsorption of pb, cu, ni, zn, and cd ions onto fgcx is spontaneous and endothermic in nature. in this investigation, an amino functionalized adsorbent was developed by grafting 4 aminobenzoic acid onto the backbone of cross linked chitosan beads. the 3 sets of beads including chitosan (cx), glutaraldehyde cross linked chitosan (ccx), and 4 aminobenzoic acid grafted.
