Abstract:

Development of bio-based filtering materials follows the need for a drastic reduction in solid particle-pollution, which is nowadays one of the largest risks for human health and state of the environment. Filtering sector currently concerns itself primarily with removal and immobilization of increasingly small particles, effectively requiring small pore size and enhanced surface area. This research work is a part of a national research and development program â�?�?Cel.Cycleâ�?, aiming at constructing materials with a hierarchical porous structure and increased active surface; in order to do this, existing and novel technologies will be employed, as well as integration of active components (inorganic particles; micro- and nano-fibrillated cellulose), leading to 3D nonwoven structures with desired functional properties. The increase of organic compounds in environment encourages also search for more efficient adsorbents used in water treatment. Clays are known as natural environmental-friendly materials with high specific surface area, used in dispersed form, for the adsorption and removal of organic pollutants, causing difficult removal from purified water. Therefore, the second part of this research is focused on preparation and characterization methods of nanocomposite clay/polymer hydrogels used for adsorption of textile dyes. Structures and functionalities of nanocomposites will be described and conditions (e.g. clay particle type and concentration, dispersing medium, monomer, cross-linker concentrations, and drying procedure, etc.) for achieving exfoliated and intercalated clayâ�?�?hydrogel structures will be discussed. In addition to functional properties of nanocomposites conditioned by the nanocopmposite, their preparation process will be discussed.
