Abstract
A process for treating colored liquid comprises a step of contacting a colored liquid and functional water generated by electrolysis of a water solution of an electrolyte under light irradiation, to decolorize efficiently and stably to a low chromaticity.
Claims36
A process for decolorizing a colored liquid comprising the steps of:
- providing functional water by electrolyzing a water containing an electrolyte;
- and
- bringing a colored liquid into contact with the functional water under irradiation with light to reduce chromaticity of the colored liquid.
An apparatus for decolorizing colored liquid, comprising a container provided with a pair of electrodes, a power source for applying a voltage to the electrodes, and a means for supplying a water containing an electrolyte to the container, a light irradiation means and a means for supplying a colored liquid to the container.
An apparatus for decolorizing a colored liquid, comprising a decomposition treatment container, a means for supplying a functional water obtained by electrolysis of water containing an electrolyte to the decomposition treatment container, a means for supplying a colored liquid to the decomposition treatment container and a means for irradiating the decomposition treatment container with light.
