Abstract: The adsorption of selenious acid by chitosan(CTS) has been investigated. The adsorption isothermal and kinetic curves have been determined. It is found that the adsorption capacity is highly affected by pH and the adsorption action fits the Langmuir model which describes the adsorption of monolayer. The IR and UV assays also indicate that the adsorption of selenious acid by chitosan is just a simple physical process instead of a chemical one.

Key words: chitosan, selenious acid, adsorption isothermal curve, adsorption kinetics
