Abstract
Abstract: Nanoparticles, with a diameters upto100nm, exhibit a heightened surface-to-volume ratio which allows a greater participation of active surface atoms, fostering improvements in material properties and enhancing implementation. The current work involves acquisition of abundantly, non-edible, and easily available agro-waste cauliflower leaves; pyrolyzed in an inert atmosphere at particular temperature to generate carbon materials. Additionally, the material is activated by using definite concentration of alkali solution followed by impregnation of copper metal and processed with annealing to obtain a desire adsorbent carbon nanomaterial. Adsorption of heavy metal ions [Ag(I)] at pH 6 gives significant result of 96% verified by ICPAES analysis. Characterization as well as morphology of adsorbent was examined through SEM and HR-TEM. Moreover, XRD revealed the presence of graphitic and amorphous carbon whereas BET prominently explained the specific surface area, pore volume and porosity of the synthesized carbon nanomaterial impregnated with copper nanometal.
