Graphite Recycling by Doping Nano-materials for Water Treatment

Abstract

This paper presents graphite recycling by doping nanosilver for water filtration because of the need for secure water for consumption. It has demonstrated the significance of looking for alternative materials that can filter water independently or in combination with other materials. Adsorbent nanomaterials have unique characteristics as compared to conventional ones due to their small size and significant surface area relative to volume ratio. In this study, an effort is made to test the usability of nanomaterials, such as graphite-doped nanosilver, as adsorbents for the elimination of different kinds of heavy metals from water. This study detects the elimination of metal ions from aqueous solutions by using modified graphite nanosheets. The shape of the synthesized graphite adsorbent nanosheet was characterized by spectroscopic analyses such as SEM and HR-TEM. The sizes of these nanocrystals are comparatively small, at about 38 nm for Ag and 56 nm for G–Ag samples, as shown by HR-TEM. The results showed that raising the duration of immersion and adsorbent quantity improved adsorption effectiveness. Chemical treatment frequently affects the surface characteristics of nanoadsorbents and considerably enhances their adsorption capacities. The metal-nanomaterial interactions, processes, and capacities of nanomaterial-based adsorption are analyzed and described in this work in a variety of experimental settings. The improved adsorbent graphite recycling showed a significant adsorption efficiency of 91.7% for heavy metals. It is vital to research ecologically friendly and sustainable applications that can lead to innovative and revolutionary water treatment systems.
