SCAVENGING/DETECTING AGENT FOR HIGH-VALENCE METAL ION

摘要

PROBLEM TO BE SOLVED: To provide a scavenging/detecting agent capable of efficiently and selectively scavenging high-valence metal ions of ≥3 in valence contained in a medium and enabling the ions to be easily detected and their concentration to be measured.

SOLUTION: The scavenging/detecting agent for metal ions of ≥3 in valence is provided, being such that a hydroxamic acid group-bearing compound is introduced into a carrier.
