BUBBLE MEASUREMENT DEVICE AND BUBBLE MEASUREMENT METHOD
This bubble measurement device for measuring bubbles moving in a liquid, is provided with: a measurement chamber to which bubbles in a liquid containing solid matter are introduced from the lower side and which is provided with a transparent inclined surface oriented obliquely downward at a position where the introduced bubbles ascend; an imaging device that captures an image of the bubbles passing along the transparent inclined surface; an introduction pipe that is disposed below the measurement chamber and that introduces bubbles to the measurement chamber; and a bubble introduction valve that is immersed in the liquid to be measured and that blocks and introduces bubbles to the introduction pipe. The opening time period of the bubble introduction valve is obtained in accordance with the shape of the introduction pipe, the properties of the liquid, and the supply amount of air supplied into the liquid. When the imaging device captures an image of bubbles in the measurement chamber, the opening time period of the bubble introduction valve is adjusted to a predetermined time period in which the bubbles and the solid matter contained in the liquid can be identified.
Provided is a lithium hydroxide production method that makes it possible to reduce the load of removing divalent or higher valent ions in an ion exchange resin. A lithium hydroxide production method according to the present invention includes the following steps (1)-(3). (1) Neutralization step: a step for obtaining a neutralized liquid by adding an alkali to a first lithium chloride-containing liquid. (2) Ion exchange step: a step for obtaining a second lithium chloride-containing liquid by bringing the neutralized liquid into contact with an ion exchange resin. (3) Conversion step: a step for obtaining a lithium hydroxide-containing liquid by subjecting the second lithium chloride-containing liquid to electrodialysis. With this production method, divalent or higher valent ions can be roughly removed in the neutralization step, and thus, it is possible to reduce the load of metal removal by the ion exchange resin.
