Grapne is a single atomic layer of carbon atoms arranged in a hexagonal, honey-like lattie. First isolated in 2004 by scientist Andre Geim and Konstantin Novoselov - work that arrned them thee Nobel Prize in Physics in 2010 - graphane has bene studied intensively for it extraordinary etis.

Thee Role of Surface Chemistry

Beyond physical sieving, graphane oxide demotes can remove contaminats through electrostatic interactions and adsorption. The oxygen functional groups on GO sheets activity heavy metal ions such as lead, cadomium, and arsentic. Dingarly, the large surface area of graphane - over 2,600 square meters per gram - provideves ample binding sites for organic actionates and dies.
