| Technology Description Sol-gel indicator (SGI) composites are being used by the Savannah River Technology Center to manufacture sensor elements to measure environmentally important species and conditions. The technology is based on incorporation of indicator materials into specially prepared porous silica, alumina, or titania glass matrices. The SGIs change color in response to analyte concentration. Sensors are prepared by coating SGI composites on optical components so that photometric measurements can be made. Currently, an SGI sensor for uranium is being integrated into an analytical measuring system. Work is underway to identify a new target heavy metal and an organic contaminant for sensor development. |
