  7. Abstract:
  8. Today, with expanding industries, wastewater treatment of them is a global problem. Heavy metal is one of the most common and most dangerous contaminants in waste water that over time, with the strict standards of output, find more effective ways of eliminating them has always been a challenge. New methods, especially in the field of adsorption have achieved promising results in many cases.
    Polymers composites are one of the adsorbent for the removal of these contaminants have been considered. In this project Aniline and composites to remove arsenic and chromium were studied. In polymers synthesis factors like type of additives and oxidizing materials strongly effected on morphology of composites and subsequently on physical and chemical propetries of composites. Therefore in this project in the first composite with the best performance in metal adsorbtion had been selected and then The effect of factors such as pH, contact time, adsorbent amount consumed, the concentration of adsorbent, the adsorption isotherms, Recovery rates and the effect of oxidation on the adsorption performance was investigated And thus the best conditions for removal of metal was reported.
    The results suggest that the additive type and amount of use it has a large impact on its performance, removal reaction is extremely dependent of the pH and the composite also shows good desorption and reuse ability
