Lithium reagent compositions, lithium reagent kit, and lithium ion measurement methods.

摘要

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 lithium reagent kit and a method for measuring lithium ion.;SOLUTION: In a lithium reagent composition, a lithium reagent kit and a method for measuring lithium ion, 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, and furthermore, a water-miscible organic solvent, a pH regulator, and a masking agent are contained.;COPYRIGHT: (C)2014,JPO&INPIT
