Abstract: A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

Abstract: A water quality measurement device 1 includes a twin tube excimer lamp 2. The inflow pipe 3 is connected to one end of the inner tube 21 of the excimer lamp 2, and the outflow pipe 4 is connected to the other end of the inner tube 21 of the excimer lamp 2. The detector 5 that measures the conductivity of sample water is interposed in the outflow pipe 4. In the water quality measurement device 1, sample water sequentially flows through the inflow pipe 3, the inner tube 21 of the excimer lamp 2, and the outflow pipe 4. Hence, the channel in the water quality measurement device 1 can be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tube 21 of the excimer lamp 2. Hence, it is possible to irradiate the sample water with UV light from the excimer lamp 2 efficiently.
