Metal nanoparticles are currently being used in many applications such as reinforcement of fabrics for anti-bacterial action, medical diagnostic devices and as catalysts. There is need to develop methods of removal and disposal of nanoparticles that may end up in wastewater. Activated carbon is a form of carbon that can be made from thermal decomposition of carbonaceous material followed by an activation step. The carbon is held together in carbon-carbon bonds that give it a structure similar to graphene. The final substance is a high surface area material with strong adsorptive properties. Au nanoparticles were synthesized using citrate reduction methods and removal from solution by activated carbon followed by using UV Vis spectrophotometry. Preliminary results show that activated carbon can be useful as a filter for nanoparticles in solution.
