Composite materials based on chitosan/amidoximated starch beads and CaCO3

Herein, beads based on chitosan and amidoximated starch were used, for the first time, as support materials for CaCO3 crystallization. The CaCO3 crystal growth was conducted by using different carbonate sources (Na2CO3, dimethyl- and diethyl-carbonates) and different strategies (fast, alternate or slow diffusion). The interaction of the obtained composite beads with Cu(II) ions was also investigated. The morphology of composite beads, before and...
