Abstract: Industrial and municipal wastewater typically contains metal ions. When these metal ions are more than allowed, they can be harmful to aquatic organisms and human health. Environmental pollution by heavy metals is one of the main environmental problems. In this study, microbial nano cellulose was used as adsorbents in removing copper from wastewater. The purpose of this study was to study the possibility or impossibility of removing heavy metal copper by microbial nano cellulose under various environmental conditions. Removal of copper under different conditions was investigated by microbial and dry microbial nano cellulose adsorbent, contact time of 30 and 60 min and ambient temperature and temperature of ?60?^?. For further investigation, flame atomic absorption spectroscopy and infrared spectroscopy as well as scanning electron microscopy were used to illustrate the structure of microbial nano cellulose. The results showed that microbial nano cellulose are suitable for the development of economical and efficient adsorbents to remove heavy metals from the aquatic environment. According to the results, the initial metal content in the solution was 1.83 ppm, which increased with increasing temperature and time of absorption. Comparison between microbial nano cellulose and dry microbial nano cellulose. The results showed that absorption in the microbial cellulose nanoparticles is more than dry, due to the microbial cellulose structure. Also, using infrared spectroscopy, microbial nano cellulose absorption bands alone and dried microbial nanoclayers were compared with each other in a heavy metal solution, and no new absorption bar was created. As a result, the absorption of microbial cellulose nanoparticles was better at higher temperatures and more time than the rest.
