Preparation of a new chitosan-based material and its application for mercury sorption

- Chitosan sponge-like structure under the form of cylindrical foam has been prepared by freeze-drying technique (holes: Ø: 10 mm; height: 10 mm).
- Preliminary tests, showed that chitosan has relatively a high selectivity to mercury Hg(II).
- pH was the most significant factor that affect the adsorption capacity.
- The application of the cylindrical foam is considered as an encouraging material from laboratory tests to industrial scale.
