In this study, the effects of nanostructure absorbent of ZnO in graphene bed for a wastewater treatment unit in weaving are evaluated. Initial analysis was undertaken to identify the existing metals and their concentration in the prepared wastewater. It was seen that the diluted solution consisted of the ambivalence ions of lead, copper, nickel, cadmium, and silver with the concentration of 73/31, 81/19, 54/6, 98/1and 76/1 milligram per liter, respectively. Trivalent chrome, with a concentration of 98/1 milligram per liter was also observed. Therefore, by adding various amounts of absorbent (20, 30 and 50 milligrams) to the wastewater sample and adjusting the PH to 5 and 6, each metal was separately absorbed.
