With lead contamination in water supply lines across this nation – and the world – some researchers are examining the possibility of using magnet-steered graphene-based microbots to scrub lead from polluted water. Wow!
In the space of a single hour, the study showed, self-propelled microbots could remove up to 95 percent of lead from water.
Lead is commonly found in wastewater from mines or factories that make batteries and electronic devices, and can pose a serious risk to public health, as the water crisis in Flint, Michigan demonstrates. Industrial activities can also contaminate water with arsenic, mercury and other metals.
