摘要：
To provide a novel copper ion indicator which is less influenced by interfering metal ions and which is useful for measurement of copper ion within a wide concentration range. The invention provides a copper ion indicator containing a compound represented by formula (1): [wherein each of R1, R2, R3, R4, R5, and R6 represents a hydrogen atom or an alkali metal atom], and a method for determining copper ion concentration, which employs the indicator.
