چکیده مقاله:

In this study, the graphene nano sheets were synthesized by the Hummer’s method. In the next stage,functionalization process of graphene nano sheets was done by Cyanuric chloride and ۱, ۳, ۴ thiadiazol ۲,۵ dithiol. In order to determine the composed functional groups and sample purification the FTIR andXRD analysis were used, also, in order to analyzing the morphology and the functionalized nanoparticlesstructure as well as determining the size of the particles the FESEM and EDX analysis were used. Theintended graphene was functionalized successfully and then was examined in the solution which containthe lead in order to determine the optimum pH, temperature, amount of adsorbent and retention time.Finally, it was observed that the optimum adsorbent condition is in pH = ۵.۳, the retention time = ۲۰minutes and the amount of adsorbent = ۰.۰۶۵. Also, the adsorbent capacity was obtained ۲۳۵ .
