      abstract     = {Water pollution is one of the major challenges facing
                      modern society because of industrial development and urban
                      growth. This study is directed towards assessing the use of
                      multiwall carbon nanotube, after derivatization and
                      magnetization, as a new and renewable absorbent, to remove
                      toxic metal ions from waste streams. The adsorbents were
                      prepared by, first oxidation of multiwall carbon nanotube,
                      then derivatizing the oxidized product with hydroxyl amine,
                      hydrazine and amino acid. The adsorbents were characterized
                      by various techniques. The adsorption efficiency of the
                      multiwall carbon nanotube adsorbents toward Pb(II) was
                      investigated. The effect of adsorbent’s dose, temperature,
                      pH, and time on the adsorption efficiency were studied and
                      the adsorption parameters that gave the highest efficiency
                      were determined. The derivatives have unique coordination
                      sites that included amine, hydroxyl, and carboxyl groups,
                      which are excellent chelating agents for metal ions. The
                      thermodynamic and kinetic results analysis results indicated
                      spontaneous adsorption of Pb(II) by the multiwall carbon
                      nanotube adsorbents at room temperature. The adsorption
                      process followed pseudo-second-order and Langmuir isotherm
                      model. The adsorbents were regenerated using 0.1 N HCl.},
