“…These materials include chemisorptions fibers and fabrics with a developed characteristics surface. Scientific researches discuss different methods for manufacturing of the ion-exchange materials such as creation of functional active groups in the fiber polymers via reactions in polymer chains [1][2], and grafting of fibers with inorganic and organic monomers with subsequent reactions in the grafted chains [3][4][5][6]. The fibers could be used as material for different S.E.…”

EMOVING the hazardous metals from wastewater especially industrial drainage is very important for preventing health problems in human beings, plants and animals. The ion exchanger has constructed as primary line of safeguards for that goal. In this study grafted polyamide-6 (PA-6) fibers with polymethacrylic acid (PMAA) was used as materials for the ion exchangers. Grafting was achieved under required time and temperature and the factors affecting the graft process were studied. The efficiency of the grafted fibers for adsorption of Cu 2+ , Pb 2+ and Cr 6+ was evaluated. The effect of adsorption parameters such as pH, duration of adsorption, initial ion concentration and the adsorption temperature on the degree of extraction (R %) and adsorption capacity (SC, mg/g) was studied. Optimization the conditions for the preparation on laboratory scale, adjustment and adaptation of these conditions to suit the production of these grafted fibers on pilot scale was accomplished.

“…A different approach to incorporation of sorption-active groups in a fibre merits special attention --the use of graft polymerization of monomers containing active groups using chemical [16][17][18] and radiation chemical [ 19] methods of initiation. This method allows obtaining modified fibres with different functionally active groups (due to the presence of a wide set of ionogenic monomers of the vinyl series) and high sorption activity (due to the distribution of the graft polymer in the surface layers of the oriented fibre).…”

Scientific concepts concerning the characteristics of graft polymerization to oriented polymeric materials and p~lymer-anal~g transf~rmati~ns ~f the graft p~lymer were elab~rated based ~n systematic studies. The principles of fabrication of sorption-active fibre materials Of different ~,pes based on graft copolymers and the most important directions of their use were formulated.The consequences of human technological activity has sharply worsened the environmental situation, making environmental protection an urgent modern problem. One direction in the complex solution of these problems is to develop highly efficient processes for scrubbing of industrial gas-air emissions and cleaning ofwastewaters. Sorption materials, used to prevent further environmental pollution and ensure rational resource management, are playing an important role in the creation of such processes.These materials include chemisorption fibres with a developed specific surface area which is more than one order of magnitude greater than the surface area of granulated sorbents. A comparison of the geometric surface area of fbres and granules gives an idea of the advantage of fibre sorbents over granulated sorbents, manifested by a higher rate of chemisorpticn and greater completeness of removal. In addition, the variety of forms of use of fibre sorbents favors the rational organization of technological processes.The analysis of the scientific and technical literature on fabrication of chemisorption fibres revealed the following methods:-spinning of fbres from blends of fibre-forming polymers with nonfibre-forming polymers containing ionogenic groups;-synthesis of fibre-forming copolymers containing functionally active groups and fabrication of fibres from them; -incorporation of functionally active groups in the fibre via reactions in the polymer chains; -modification of fibres by graft polymerization of ionogenic and nonionogenic monomers with subsequent polymeranalog transformations of the graft chains.Spinning of chemisorption fibres from polymer blends is a relatively simple method. However, the difficulties of obtaining stable spinning solutions from blends of fibre-forming and nonfibre-forming polymers and the possibility of washing out the sorption-active component of the fibre make it necessary to conduct an additional operation of formation of a threedimensional spatial network in the fibre [1,2]. Moreover, this method can be used together with other variants for production of sorption-active materials.The method of spinning fibre chemisorbents from copolymers with chemically active groups in the main chain has been widely used in fabrication of chemisorption fibres of the VION group [3,4]. In this case, acrylonitrile is usually usedas the fibre-forming component, and the composition of the ionogenic comonomers responsible for incorporation of sorptionactive groups in the structure of the fibre is relatively varied. This concerns methylvinylpyridine (MVP), vinylimidazole, sodium p-styrenesulfonate, and others [3,[5][6][7][8]. The fibres...
