Abstract: The thiosemicarbazide-cellulose was prepared and its static adsorption properties such as capacities, kinetics and isotherm for Pb2+,Ni2+,Co2+ were studied. The factors to influence adsorption process were also investigated. The results indicated that the thiosemicarbazide-cellulose has selected adsorption property to Pb2+,Ni2+,Co2+. The adsorption isotherm approximately fit the Freundlich equation within the range of experimental concentration. The ion bond and the conjugant bond were formed between the thiosemicarbazide and Pb2+,Ni2+,Co2+. The chemical adsorption was dominant.

Key words: thiosemicarbazide-cellulose, epichlorohydin, adsorption
