SMART MEMBRANES FOR NITRATE REMOVAL, WATER PURIFICATION, ANDSELECTIVE ION TRANSPORTATION

摘要

A computer designed nanoengineered membrane for separation of dissolved species. One embodiment provides an apparatus for treatment of a fluid that includes ions comprising a microengineered porous membrane, a system for producing an electrical charge across the membrane, and a series of nanopore s extending through the membrane. The nanopores have a pore size such that whe n the fluid contacts the membrane, the nanopores will be in a condition of double layer overlap and allow passage only of ions opposite to the electric al charge across the membrane.
