| titleOfInvention | Method and apparatus for in-situ measurement of ion concentration in solution |
| abstract | (57) [Summary] [Problem] To measure the absorbance of a solution using the principle of the attenuated total internal reflection method, a true in-situ measurement can be performed, and furthermore, the size of the apparatus can be reduced. Provided is a method and apparatus for in-situ measurement of ion concentration in a solution, which enables accurate measurement of absorbance even when the ion concentration in the solution is high or insoluble particles or bubbles are present in the solution. SOLUTION: A probe 1 composed of an optical fiber composed of a core and a clad is partly removed to form a measurement part 2 from which a core is exposed, and the measurement part is immersed in a solution 5 to be measured. And connect both ends of the probe to an absorptiometer 3 And the light emitted from the spectrophotometer is guided from one end of the probe to the measuring section, and the reflected light totally attenuated by the measuring section is made incident on the absorptiometer from the other end of the probe, thereby reducing The attenuation characteristic of the reflected light due to the reflection is determined, and the ion concentration in the solution to be measured is measured based on the attenuation characteristic. |
