Abstract | We perfonned a series of esperiments to investigate the influence of different salts dissolved in water on the corona discharge patterns around water drops and on subsequent image formation. Considering our research needs, we developed a special method of corona discharge electrography of water drops with computer analysis of images. Our method differs from the usual corona discharge photography (known also as Kirlian photography) in the mechanisms of image formation. It relies on chemical reactions and deposition of substances transponed in the discharge area rather than on the usual photoreactions. Higher reproducibility of results is achieved through simultaneous imaging and comparing two drops from different samples. In the presented experiments we compare different salt solutions with distilled water and between themselves. Results show distinct behavior of corona discharse patterns as regards ionic composition of salts, both radially and angularly. The present investigation may also shed some light on the problem of the influence of a different ionic composition in using this type of method for diagnostic purposes. | |
