| Title: | APPARATUS FOR DETECTION OF SOIL AND WATER CONTAMINANTS BY ORGANIC COMPOUNDS | |||||||||||
| Abstract: | Apparatus and method for detection of organic contaminants in a sample of water or soil through extraction of the contaminants with an organic solvent followed by addition of a Friedel-Crafts Lewis acid catalyst to the extract to produce a reaction precipitate having a characteristic color indicative of the type and quantity of contaminant. The apparatus has a housing (1) with an opening to receive a test tube (2) containing the reaction precipitate into a chamber (6). Within the housing (1) are a light source (11), a fiber optic probe (8-10) and a CCD spectrometer (12) to illuminate and record the reflected light from the reaction precipitate in the test tube (2). The apparatus also has an external computer (14) for processing the recorded signal to determine the type and quantity of contaminants present in the sample. | |||||||||||
