A Hong Kong-based company, Dunwell Enviro-Tech, has engineered a recyclable nanoparticle that not only attracts metal ions and organic molecules, but can release the contaminant and be used again. The company believes the product, developed with the Hong Kong Polytechnic University, is set to revolutionize waste water management. The technology could also be used in plating and mining operations, in which large quantities of water are used, and released back into the environment. The nanoparticles could remove the polluting metals and improve the water quality. According to Daniel M. Cheng, managing director of Dunwell, "[W]ith this technology, they can treat the water and recover precious metals at the same time. The function of this type of nano is to act as a sort of transport vehicle that grabs the precious metals, releases them and goes back to work. They are almost like microscopic trucks." The product was released last year and the company hopes to make it available worldwide. The article can be viewed online at the link below.
