Title: Nanoparticle sorbent for efficient mercury remediation from contaminated water

Abstract

A new class of sorbents for the removal of mercury from contaminated water. The optimum structure of the sorbent particles and a method to produce the same is described. The newly developed carbon-based particles are differentiated from other sorbent particles by their high accessible surface area and high affinity towards mercury ions that leads to faster and higher mercury adsorption. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.
