Iron-based metallic systems: an excellent choice for sustainable water treatment

摘要

Abstract The permanent quest for affordable, applicable and efficient technologies for water treatment has culminated in the use of metallic elements as universal remediation materials. Contaminants of concern are biological (e.g. bacteria, viruses), chemical (organic and inorganic compounds) and physical (e.g. color, turbidity) in nature. The current classification of chemical contaminants is confusing as it accounts for (i) their origin/use (e.g. dyes, pesticides), (ii) the time scale at whic.
