| Abstract: | Ethylenediamine chelating bacterial cellulose has been synthesized by bacterial cellulose.The product is characterized by the infra-red spectroscopy and elemental analyser.Its characteristics,such as adsorption kinetics and adsorption isotherms for copper ions are studied.The results show that the adsorption kinetics can be described by pseudo-second-level velocity equation.The adsorption equilibrium accords with Freundlich isotherm adsorption equation.The adsorption and desorption properties of ethylenedia... |
