dc.description.abstractLignocellulosic residues are interesting materials for the production of heavy metal adsorbents for aquatic systems. Whole fibers taken from coconut (Cocos nucifera) husks were functionalized with the thiophosphoryl (P=S) group by means of the direct reaction with Cl3P=S, (CH3O)2ClP=S or (CH3CH2O)2ClP=S in order to obtain an adsorptive system for ‘soft’ metal ions, particularly Cd2+. These functionalized fibers (FFs) were characterized by means of elemental analysis, infrared spectroscopy, thermal analysis and acid–base titration. Adsorption isotherms for Cd2+ fitted the Langmuir model, with binding capacities of 0.2–5 mmol g 1 of FF at 25 C.en_US
