Abstracts:

The possibility of spectral analysis of conductive liquids in self-oscillating regime of diaphragm discharge under voltage less then 1 kV was shown experimentally. The limits of detection of potassium and copper in solutions on the level of 50 mg/l were achieved. The graduation dependencies of the relative intensity of potassium on wave length 766,49 nm and copper on wave length 510,55 nm on their mass concentrations were obtained which are described by logarithmic equation of Lomakin-Shaybe. The temperature of discharge plasma which is equal to 2200 K was defined by the technique of spectral pyrometry.
