Removal of lead and kadmiyum(Pb2+, Cd2+) from waters using naturalwaste adrorbant

Water pollution caused by heavy metals are lethal effects on living organisms and leads to serious environmental problems. Although these particular low amount of Pb2+ and Cd2+ environment has negative effects on living organisms and even if over a certain value shows no toxic effects. Therefore, the removal of the metal ions prior to release into the environment of waste is significant. The growing problem of waste removal, waste polluting the environment as found in nature has become one of the chestnut shell material suitable for the use of biyoadsorbent wastewater treatment. Alternatives to this process, inexpensive, non-toxic, the use of biyoadsorbent more environmentally friendly and more economical than other methods as well. vegetable waste and residues, is revealed as no more than the amount of various food processing process. This residual waste and proper evaluation of the country's economy is very important in terms of prevention and environmental pollution. For this purpose, Pb2+ and Cd2+ urchin shells with a solution containing ions was treated in different periods and Pb2+ optimum period of 10 min to a solution, Cd2+ The optimal time for was found to be 60 min. Then, the amount of adsorbent adsorbent onto the metal binding capacity, pH, temperature and Pb2+ and Cd2+ ions were investigated the effects of concentration. In addition, the results obtained from adsorption studies Freundlich, Langmuir isotherm conformity analysis and adsorption kinetics were also investigated.
