| titleOfInvention | Simple measurement method of metal ion concentration using hydrophobic colloid |
| abstract | PROBLEM TO BE SOLVED: To provide a method for quantifying a metal ion concentration. SOLUTION: An iron (III) hydroxide colloid solution containing Fe3 + prepared by adding an iron (III) chloride solution to boiling water is added to a sample solution containing metal ions to generate a mixed solution, and then a paper One end of the qualitative filter paper for chromatography is immersed in the mixed solution and left for a predetermined development time in an open system, and the distance L from the lower end of the filter paper to the development front line and the lower end of the filter paper to the upper end of the colloidal layer The distance hc is measured, the maximum value of the ratio hc / L is obtained, and the known metal ion concentration is prepared in advance using the measurement results performed by the same procedure as above using a plurality of metal ion solutions with known metal ion concentrations. The step of determining the metal ion concentration of the sample solution by using the calibration line of the maximum value of hc / L with respect to the metal ion solution of the concentration is included.
