Abstract :
Chromium is a relatively common element, naturally occurring in rocks, soil, plants, animals, and in volcanic dust and gases. Oil and coal contain traces of chromium (III). Chromium is Mainly found as the chromium (III) form in nature and rarely as chromium (VI) compounds. Chromium (VI) is very toxic and all released from industries .Breathing high levels of chromium (VI) can cause irritation to the nose, such as runny nose, nosebleeds, and ulcers and holes in the nasal septum. Ingesting large amounts of chromium (VI) can cause stomach upsets and ulcers, convulsions, kidney and liver damage, and even death. In this project were studied the separation of ion heavy metal chromium (VI) Using new filamentary adsorber for removal of contaminants in environmental. The purpose of this research work is to build a new nano-absorber, GZ-BAKI-TAC-Cr-88, for the adsorption of water soluble chromium ions in polluted water. The sorbent for separation are made by using sodium alginate, Calcium chloride and Beshel Tire activated carbon with nano-holes. The filamentary length of adsorber was 10 cm and 300 μm in diameter in wet state. The tests were done in discontinuous system. The adsorption capacity and the kinetic of maximum percent by metal concentrations in 50,100,150and 200 ppm were studied. The amount of chromium uptake was 75.928 ,134.416, 168.667,and 240.05 respectively. For kinetic reaction times, 10, 20, 30,40,50,60 and 120 minutes were selected. The maximum adsorption of chromium (VI) achieved(q) 240.05 in 120 minutes with 200ppm primary concentration of chromium. Results indicate that the new adsorber calcium alginate filamentary containing activated carbon with nano-holes has good adsorbing character for removal of chromium (VI) in polluted effluent .With increasing of activated carbon in sodium alginate increased the amount of chromium (VI).
