Title:
ANALYSIS SYSTEM, ANALYSIS METHOD, AND ANALYSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/286851
Kind Code:
A1
Abstract:
Provided is an analysis system equipped with a terminal comprising an element-acquiring part for acquiring the amount of an element contained in an object in an electrolysis tank, and a server comprising a receiver for receiving the amount of the element acquired by the element-acquiring part, and a state-analyzing part for analyzing the state of the object on the basis of the amount of the element received from the receiver. The electrolysis tank may comprise an ion exchange membrane, and a positive electrode chamber and a negative electrode chamber partitioned by the ion exchange membrane. An aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide may be introduced in the positive electrode chamber, and an aqueous solution of an alkali metal hydroxide may be drawn out from the negative electrode chamber. The state-analyzing part may: analyze the state of the object on the basis of a first predefined relationship between the current efficiency of the electrolysis tank and the amount of the element, analyze the state of the object on the basis of a second predefined relationship between the voltage of the electrolysis tank and the amount of the element, or analyze the state of the object on the basis of a third predefined relationship between the chlorine ion concentration in the aqueous solution of the alkali metal hydroxide and the amount of the element.
