Water is essential for all forms of life. The single most important technological need for developing countries is the development of safe, low-cost, purification methods to disinfect and detoxify water. The core of the research at The Institute for Green Science (IGS) at Carnegie Mellon University, Pittsburgh, PA, USA is based on the development of tetra-amido macrocyclic ligand (TAML®) catalysts for the activation of hydrogen peroxide in order to destroy chemical pollutants in water.

The research groups of Terry Collins and Alexander Ryabov at IGS, in collaboration with the group of Sayam Sen Gupta, CSIR National Chemical Laboratory, Pune, India, have studied and compared the catalytic activity and operational stability of a series of fifth generation of TAML activators in the oxidation of Orange II by hydrogen peroxide. One of the members of this series performs very well at pH 7, the most common acidity conditions for water treatment.

They have found that the introduction of a nitro substituent is beneficial for increasing the operational stability of TAMLs in oxidations by H2O2. In addition, they have shown that one of the members of this series, with a biuret functional group in the macrocycle, performs very well at neutral pH, the most common acidity conditions for water treatment.
