Water and wastewater: Getting the arsenic out

July 2009
InTech;Jul2009, Vol. 56 Issue 7, p11
The article focuses on a new membrane material being developed by International Business Machines Corporation (IBM) that is effective at cleansing drinking water of arsenic contaminants. It says that the material is from polymers created by Allen and Central Class. Its pH sensitivity is said to be the key to the material's performance while other membranes are not capable to operate in the primary conditions necessary to ionize arsenic. IBM plans to try the membranes in Bangladesh, where there are many people who drink water infected with arsenic.
