Southwest Sciences proposes the development of an optical, near-ultraviolet chlorine dioxide (ClO2) sensor having a measurement range of about 0.01 to 2000 ppm with a response time of less than 10 seconds. The sensor will be compact—about the size of a 1-quart milk carton including electronic and optics, operate at low power, and be outfitted with a wireless communications interface to permit re ...

Using the unique spectral characteristics of its proprietary fractal-microcavity composite, LaSys, Inc., will perform the proof-of-concept research required to develop an ultra-sensitive optical detector of low concentration of arsenic in water based on the Raman effect. The Phase I technical objectives are designed to demonstrate that fractal microcavity composite-surface-enhanced ...

Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...

The photographic industry consumes about 70 million troy ounces of silver annually. The technology used to recover the silver from concentrated solution is more than 40 years old. However, investigators project that, based on industry experience, as much as 20% of this silver is lost in the wash water and goes unrecovered. The toxicity of silver in the effluent is a growing concern in the United ...
