Material Characterization

Material characterization, also known as surface interaction processes, use a solid surface to remove constituents from solution. Surface interactions used in desalination strategies include:

Charged surfaces which draw ions of the opposite charge from solution
Hydrophilic surface-water interfaces to exclude colloids
Ion exchange surface interactions where a less obtrusive ion is exchanged for a problem ion

Research on surface interaction processes includes research into electrets and the aqueous boundary effect on colloid separation.
