[Problem] 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 biosample 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 determining the amount of lithium ions using the composition. [Solution] The lithium reagent composition comprises F28 tetraphenylporphyrin as a chelating agent, a water-miscible organic solvent, a pH regulator, and a stabilizer. The method and device for determining the amount of lithium ions employ the composition. |
