| titleOfInvention | Cation measuring tool and cation quantification method |
| abstract | (57) [Summary] [Structure] An ionophore capable of forming a complex such as bis [(benzo-15-crown-5) -4'-hydroxymethyl] pimelate cation, and a cationic dye and a fat-soluble anion. A cation measuring instrument comprising an organic liquid phase containing both of the salts of, for example, tetrakis (p-chlorophenyl) borate and toluidine blue. [Effect] Since the cation measuring instrument of the present invention uses an ionophore capable of forming a complex with a specific cation, It can respond to specific cations in a liquid sample with good selectivity. Also, the amount of change in absorbance is large, and the pH It is possible to quantify the cation concentration with a small error because, for example, the influence on the absorbance change response is small. Furthermore, the cation measuring instrument of the present invention can color the liquid sample solution to be measured. Therefore, there is no need for a device dedicated to a cation measuring tool, and the cation can be quantified by measuring the degree of coloring of a liquid sample by a commonly used absorption spectrum measuring device. |
