Description:
Developments in on-site spent solvent recovery have implications for reduced environmental pollution in the dry cleaning, furniture and paint manufacturing industries as well as in a range of commercial services. Effluents from solvent recovery operations include fugitive emissions, vent stack gases and water/solvent mixtures. At present, the scale of solvent-recovery operations in certain industries is too small to allow cost-effective application of gas or liquid chromatographic instrumental methods, yet the total volume of pollutants discharged from these operations is environmentally significant. To remedy this situation, this proposal suggests the development of low-cost continuous solvent monitors based on near-infrared fluorescence. The innovation contained in the proposal is the combination of sensitive diode laser excited fluorescence methods with integrated methods of instrument design to achieve the Phase I Technical Objectives, which include:
- evaluation of near-infrared fluorophores for solvent analysis,
- design of an integrated laser excited fluorescence analyzer, and
- acquisition of families of test data to provide information for use in instrument optimization and extensive field-testing in Phase II of the program.
