Abstract

Described herein are compositions and methods useful for the purification of aqueous fluids using dendritic macromolecules. The process involves using dendritic macromolecules (dendrimers) to bind to or chemically transform solutes, and a filtration step to produce fluid from which solutes have been removed or chemically transformed. Examples of dendrimers that may be used in the process include cation-binding dendrimers, anion-binding dendrimers, organic compound-binding dendrimers, redox-active dendrimers, biological compound-binding dendrimers, catalytic dendrimers, biocidal dendrimers, viral-binding dendrimers, multi-functional dendrimers, and combinations thereof. The process is readily scalable and provides many options for customization.
