Opis:Organic wastes such as wood, hair, feathers, exoskeletons of crustaceans and molluscs or even water melon rind represent some examples of valuable and abundant sources of natural polymers such as cellulose, keratin and chitin, which were already extensively exploited for preparation of novel bio-composite materials. Application of green chemistry approaches for their synthesis makes such bio-composites really sustainable materials with several interesting properties for different applications, including those in environmental technology. In this review, synthesis of novel bio-composites based on cellulose (CEL), chitosan (CS - chemically modified chitin) or keratin (KER) and their potential for application in environmental technology will be presented. The synthesis is based on dissolution of bio-polymers in ionic liquids. This is the crucial step in the synthesis of such materials, which at the same time makes the process completely recyclable with regard to the solvents. The tensile strength is regulated by the proportion of CEL in the material, while higher proportions of CS were shown to add to the adsorptive and antimicrobial activity of the material [1]. Antimicrobial activity was also observed for CEL:KER materials and was further improved by decorating the bio-composites with silver or gold nanoparticles [2]. Our research has shown high potential for application of synthesised bio-composites in environmental technologies including removal of toxins or killing of pathogens in water. It was demonstrated that CEL:CS composites can remove up to 96 mg of microcystin per gram of composite, which is almost 5 times higher than best known adsorbent for microcystin [1]. On the other hand CEL:KER composites with incorporated Ag0 nanoparticles have shown up to 6 logs of reduction in the number of bacteria (99.9999% growth reduction) of bacteria such as E. coli which is a frequently encountered pathogen in wastewaters [2].
