Abstract
It is known that the high amounts of copper in water are harmful to the living system and the environment. The removal
or recovery of Cu(II) in water is important in many respects, such as being a precious metal. In this study, a bionanocomposite material was produced from bio-waste material and silver nanoparticles and used as a bio-adsorbent for
the removal of Cu(II) from model aqueous solutions. Since the optimization study of many factors affecting the removal
process with bio-adsorption will cause long time and financial loss with classical methods, the effect of factors on bioadsorption and the interaction between factors have been carried out with the Experimental design method. With 23
full
factorial design models, the effects of 3 factors (time, amount of bio-adsorbent, initial Cu(II) concentration) on the bioadsorption process were examined and their optimum values were found. From the results obtained, the percentage of
Cu(II) removal of the bio-nanomaterial from aqueous solutions and the capacity of the bio-adsorbent were determined
