PROBLEM TO BE SOLVED: To provide a lithium reagent composition for use in determining the concentration of lithium, with which it is possible to immediately determine the amount of lithium contained in an aqueous solution such as a biological sample or an environmental sample by means of a simple colorimeter or ultraviolet/visible spectrophotometer and which renders visual determination possible, and a method and device for measuring lithium ion using the same.SOLUTION: A method and device for measuring lithium ion, includes contact with an aqueous solution in which a compound represented by a structural formula in which all hydrogen bonded to tetraphenylporphyrin carbon is replaced with fluorine is used as a chelating agent, in order to measure coloring of a lithium complex or spectra other than Soret band of a lithium complex. |
