摘要

PROBLEM TO BE SOLVED: To provide a reagent for analyzing light absorption that can precisely measure the concentration of halide ions, the concentration of azide ions, and the concentration of thiocyanic acid ions with high sensitivity, by using a light absorption luminous intensity analyzer that can be easily maintained and managed, and to provide a method for analyzing the light absorption of halide ions, a method for analyzing the light absorption of azide ions, and a method for analyzing the absorption of thiocyanic ions.;SOLUTION: A -cyclodextrin derivative or a -cyclodextrin derivative, in which at least 2, 3-position hydroxyl groups in each glucopyranose group are substituted with a methoxy group, contains a clathrate complex containing anionic iron porphyrin (III) complex and is adjusted to be in the acidic region.;COPYRIGHT: (C)2005,JPO&NCIPI
