| titleOfInvention | Simple quantification method and simple quantification device for phosphate concentration in silver plating solution |
| abstract | (57) [Abstract] [Purpose] To provide a simple quantitative method and a quantitative apparatus therefor, which enables rapid and highly accurate quantitative determination of phosphate concentration in a silver plating solution using a simple measuring apparatus. thing. [Composition] A certain amount of silver plating solution containing phosphate was sampled, After decomposing the cyan complex salt in the liquid, silver nitrate was added to adjust the pH to 5 to 7 to generate a precipitate of silver phosphate, which had a filter at the bottom and a transparent cylinder with an open upper end with a scale and its holding. A silver plating solution containing a precipitate of silver phosphate is injected into the transparent cylinder of the simple quantitative measuring device of the present invention composed of members from its open end, solid-liquid separation is performed by filtration, and the silver phosphate precipitate deposited on the upper surface of the filter. A simple method for quantifying the concentration of phosphate in the silver plating solution, which measures the height of deposition and measures the concentration using a calibration curve prepared in advance. |
