Embodiment approach 1

[0083] Embodiment 1 of the present invention will be described in detail below.

[0084] The present invention relates to a high-purity acid or alkaline electrolyte solution generation device. In the description, if any one of the acid or alkaline electrolyte solution is described in detail, it is not necessary to describe both of them in detail. It is understandable, and for further succinct and clear description, in principle, the device for generating a high-purity alkaline electrolyte solution is described.

[0085] The accompanying drawings showing the best mode of implementation of the present invention are figure 1 , therefore, with figure 1 Describe the center.

[0086] Electrolyte solution generating device 1 has the following devices as a main structure: a tank 121 as a cation supply unit; a container 123 connected to the tank 121; an ion exchanger layer stored in the container 123, for example, a bead-shaped ion exchange resin layer 125A (cation exchange resin), ...

Embodiment approach 2

[0111] Then refer to Figure 5 , the electrolytic solution generator 1a according to Embodiment 2 of the present invention will be described. The electrolytic solution production device 1a of the present embodiment is a modified example of the electrolytic solution production device 1 of the first embodiment, so the following description will focus on the differences from the first embodiment. Figure 5 neutralize figure 1 The same configurations use the same symbols, and their descriptions are omitted.

[0112] Such as Figure 5 As shown, in the electrolytic solution generating device 1a, the second layer is an ion exchanger, such as an ion exchanger 125b obtained by laminating liquid-permeable ion-exchange membranes, and further newly added ion exchangers, such as bead-shaped ion The exchange resin layer 125C is formed into three layers, thereby forming the acid or base generating part 122 . The first inlet 123a is provided facing the ion exchange resin layer 125C, and i...

Embodiment approach 3

[0119] Then refer to Image 6 , the electrolytic solution generator 1b according to Embodiment 3 of the present invention will be described. The electrolytic solution production device 1b of the present embodiment is a modified example of the electrolytic solution production device 1 of the first embodiment, so the following description will focus on the differences from the first embodiment. Image 6 neutralize figure 1 The same symbols are used for the same configurations, and descriptions thereof are omitted.

[0120] Such as Image 6 As shown, the electrolytic solution generation device 1b does not use the tank 121, and is adjacent to the ion exchange membrane 127a, and an ion exchanger, such as a bead-shaped ion exchange resin layer 125E, and a durable ion exchanger, such as an ion exchange resin layer 125E, are provided on the outside thereof. An exchange membrane 127c, and an anode 131b; and an electrolyte stock solution supply device 171 composed of an electrolyte s...

Abstract

Disclosed is a device that is for generating a highly pure electrolyte solution, eliminates impurity ions derived from an ion source that becomes a raw material solution, and prevents contamination by an active material or a gas generated by the electrode reaction at an acid- or base-generating section. The device is primarily characterized by: the section for generating the acid or base that is aimed for being formed at a portion at which ion-exchange bodies having differing polarities are stacked; ions separated from pure water at an ion interface and an ion source that forms the acid or base that is aimed for and that is supplied from the outside being a pair of ion sources; the ions being moved crossing the direction of water flow by means of an electric field; discharge to the outside of the system resulting from electroosmotic flow being promoted in the vicinity of a pair of electrodes; and collectively, an ion-exchange membrane being formed that exerts electrostatic repulsion that prevents impurities such as gases generated by water electrolysis arising at the surface of the electrodes from contaminating the generated solution.

Description

technical field [0001] The present invention relates to a high-purity electrolytic solution generating device. Background technique [0002] The present invention relates to a device for generating high-purity electrolyte solution widely suitable for chemical analysis, synthesis, and routine treatment, and particularly provides a device for generating an eluent suitable for use in ion chromatography (device). The eluent is usually fed to the separation column together with the sample containing the ion to be detected. Then, the adsorbed detection target ions are eluted after a certain period of time by utilizing the adsorption equilibrium with the adsorbent packed in the separation column. [0003] Therefore, according to the type of ion to be detected, an acid / alkaline electrolyte solution suitable for eluting the ion is selected as the eluent, and sodium hydroxide, potassium hydroxide, lithium hydroxide, and hydroxide are usually used in anion analysis. For bases of alka...
