The construction of nanoporous metal-organic frameworks (MOF) by copolymerization of organic molecules with metal ions has received widespread attention in recent years.
Compared to currently available oxidative processes, this reductive water treatment process dramatically improves the efficiency of treatment for nitro-containing compounds (e.g., ordnance and energetic compounds); halogenated compounds (such as CCl4); and others containing electron-withdrawing substituents such as sulfonate, nitrile, and carboxylate. It is a cost-effective treatment that can be added to existing oxidative water treatment processes.
This patent-pending purification technology offers a more environmentally friendly and economically competitive method for purifying drinking water supplies.
This patent-pending purification technology is a means of activating a ceramic substrate and preparing a chitosan gel that coats the surface of the substrate as well as its interstitial spaces. When used in water purification, this biosorbent provides a more efficient and less expensive method for removing heavy metals and other contaminants from water.
This new technology provides a procedure, chemistry, and apparatus for rapid on-line concentration and HPLC-based separation of inorganic and monomethyl mercury in natural water, environment and tissue samples. This technology offers substantial improvement in time, cost, and labor required to complete the analysis.
Researchers at the University of Illinois at Urbana-Champaign have developed a new technology capable of effectively detecting and quantifying metal ions in a sample by color changes. Accurate, versatile, and inexpensive, this technology uses the catalytic DNA-directed assembly of gold nanoparticles and its associated color changes to determine the presence and concentration of a particular metal ion. The sensor works like a pH paper and yet can detect a diverse range of analytes.
