摘要：

Green chemists have recently created enzyme-like catalysts called tetra-amido macrocyclic ligand activators (TAMLs) that are capable of destroying stubborn pollutants by accelerating cleansing reactions with hydrogen peroxide and other oxidants. When applied to the wastewater from pulp mills, TAMLs have been shown to reduced staining and hazardous chemicals. TAMLs could also be used to treat runoff from agricultural waste lagoons as well as residential sewage, which contains dyes from washing machines and traces of harmful pharmaceuticals that are excreted in human urine. These catalysts may also someday be used to disinfect drinking water and clean up contamination from bioterror attacks.
