Abstract:

Crosslinked chitosan salicylaldehyde Schiff base microspheres were firstly prepared under microwave irradiation, with glutaraldehyde as the crosslinking agent. The structure and morphology of the product were then characterized by means of FT-IR, XRD and TG, etc. Moreover, the adsorption capacities of the product for some metal ions were investigated, and the results were compared with those of the microspheres produced by the traditional water-bath heating method. It is indicated that  microwave irradiation remarkably accelerates the reaction and improves the yield ;   as illustrated by FT-IR, XRD and TG results, the structure of the product accords well with the expectation due to a successful graft crosslinking of chitosan; and   the microsphere adsorbent prepared by means of microwave irradiation is uniform in size and is of an increased specific surface area and an remarkably-increased adsorption capacity for Pb2＋ and Cd2＋

Key words: chitosan, microwave irradiation, microsphere, adsorption
