| Abstract |
Light scattering by individual particulates is used in a multiple-detector system to categorize the composition of suspended solids in terms of broad particulate categories. The scattering signatures of red clay and taconite tailings, the two primary particulate contaminants in western Lake Superior, along with two types of asbestiform fibers, amphibole, and chrysotile, were studied in detail. A method was developed to predict the concentration of asbestiform fibers in filtration plant samples for which electron microscope analysis was done concurrently. Fiber levels as low as 50,000 fibers/liter were optically detectable. The method offers a fast and inexpensive means for measuring, either on a continuous basis or as discrete samples, the fiber levels of filtration plant output. Further calibration of the instrument could enable analysis for other specific particulate contaminants as well. |
