This work investigated the ability of maleic acid anhydride grafted cellulose functionalized with thiourea (Cell-THU) to adsorb Cu (II), Mn (II), Cd (II), Fe (III) and Pb (II) ions from aqueous solution. Using a variety of conditions including adsorbent dose, pH, contact time, metal cations concentration and temperature at 500 rpm, the process of adsorption for this produced adsorbent to remove th...
