that removes arsenic from water. SenGupta and Greenleaf wrote an article about their method that was included in a book, Environmental Separation of Heavy Metals: Engineered Processes, that was edited by SenGupta and published in 2001. SenGupta and h...
Carnegie Mellon researcher tests tools for protecting Anacostia River ecosystem from PCBs
...diment-capping mat contains a thin layer of carbon sorbent
particles embedded in a geofabric mesh. This is one of the three "active'' capping technologies currently being demonstrated side-by-side in the Anacostia. "This thin reactive core mat (RCM), which can be rolled out and placed within a conventional ...
Natural mineral locks up carbon dioxide
...ace area of the silicon dioxide makes it a natural sorbent
for capturing more carbon dioxide and sulfur dioxide," says Maroto-Valer. The researchers have not yet tested the process on a working coal-fired stationary boiler, but they are working on developing a reactor in the laboratory that can continuously...
