Abstract: PROBLEM TO BE SOLVED: To produce highly oxidative water containing ozone and the like in excellent electrical efficiency with high productivity by dissolving an oxygen- rich gas in water under high pressure, then lowering the pressure to generate microfine bubbles of the oxygen-rich gas and exposing the microfine bubbles to the pulsed electric discharge. SOLUTION: Water is introduced into a high-pressure tank, an oxygen-rich gas is blown from a high-pressure bomb 6 through an aerator 7 into the water in microfine bubbles so that the oxygen-rich gas is dissolved in the water. At this time, the pressure in the high-pressure tank is measured with a pressure gauge 5 to adjust the pressure to several to several tens atmospheric pressure. The water saturated with oxygen-rich gas is transferred to the low-pressure tank 2, the pressure-reducing valve 9 is opened to reduce the pressure in the low-pressure tank. At this time, the oxygen-rich gas dissolved in the water is supersaturated with the oxygen-rich gas to generate microfine bubbles wholly in the water.  High-voltage pulses are applied from the pulse power supply to the electrode 3 to generate ozone whereby the objective high-oxidative water including high concentrations of ozone and/or OH radical is obtained.

Filed: 1990-07-06
Abstract: PURPOSE:To enable simultaneously analyze a sample in which hydrogen coexists, with one time of sample injection by analyzing synthetic air and converting hydrogen in it to hydrocarbon to make a flame ionization detecting. CONSTITUTION:A sample gas of synthetic air injected from a sample injecting port 3 is sent to a column for analyzing 1 by He gas and separated in the order of H, O and N to be exhausted from a column 1. The H flows in first to a sample cell 2b of a heat conductivity detector 2, but can be detected by the detector 2 because the heat conductivity is near it of carrier gas He. The H flowing out from the cell 2b flows in to a catalyst furnace 5 for hydrogen- hydrocarbon converting and is mixed with the CO sent from a branch tube 4 to be converted into hydrocarbon. The hydrocarbon flows in to a flame ionization detector 6 to be detect. The O and N flowing out from the column 1 after the prescribed recess time are detected by the detector 2 because the heat conductivities differs with it of the carrier gas He. Therefore, a sample containing H can be analyzed by one time of sample injection.
