Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method and system for quantifying chelators, which allow for easily determining the presence/absence of a chelator in a solution and easily and accurately quantifying the chelator in the solution.SOLUTION: A chelator quantification method comprises steps of; mixing a chelated measurement target substance with water, and then removing incineration ash therefrom to produce a solution; adding a dispersant for promoting dispersion of predetermined amounts of metal ions and insoluble compounds to the solution to produce a mixed solution; and quantifying a chelator in the mixed solution on the basis of turbidity measurement of the mixed solution.SELECTED DRAWING: Figure 2
【課題】容易に溶液中のキレート剤の有無を測定でき、且つ溶液中のキレート剤を容易且つ精度よく定量できるキレート剤の定量方法、及びキレート剤定量システムを提供できる。【解決手段】キレート剤の定量方法は、キレート処理が行われた測定対象物を水に混入した後、該焼却灰を除去することによって溶液を作成する工程と、所定量の金属イオン及び不溶性化合物の分散を促進させる分散剤を溶液に加えて混合液を作成する工程と、混合液の濁度の測定に基づいて、混合液中のキレート剤を定量する工程と、を備える。【選択図】図2 |
