In this research, a new method that used graphene oxide (GO) nanosheets melamine butanedioic acid (GO-MB) composites and derivation of poly (Styrene–alternative-maleic anhydride) (SMA), (SMA + melamine-butanedioic acid) (SMA-MB) is presented as sorbents for the elimination of zinc(II) ions from aqueous solutions. The adsorbents have the sufficiency to adsorb the zinc(II) ions. Through immobilizing the melamine-butanedioic acid onto GO nanosheets and SMA-MB, the desired composite was synthesized and identified by field emission scanning electron microscopy (FE-SEM) and fourier transform infrared (FT-IR) spectroscopy techniques. Some experimental parameters including, pH, concentration of the aqueous solution of zinc(II) ions, the content of the zinc(II) ions, the grapheme oxide-melamine-butanedioic acid, and SMA-MB were optimized. The results showed that, the adsorbents were matched with langmuir isotherm. It was also revealed that the uptake efficiency of zinc(II) ions considerably increased after immobilization of melamine-butanedioic acid on the GO nanosheets and SMA. These adsorbents were also shown to be very suitable to remove the zinc(II) ions from aqueous solutions.
