Product Description
Bathocuproinedisulfonic acid is a water-soluble analog of bathocuproine that emits fluorescence under UV light. Since the Bathocuproine-Cu(I) complex formed by this analog is water-soluble, Cu(I) can be determined by direct measurement of the assay solution at 483-522 nm without solvent extraction. The molar absorptivity of the bathocuproinedisulfonic acid-Cu(I) complex is 1.2×104. Dr. Faizullah developed a system to quickly determine Cu(I) at around 30 ppm by using Bathocuproine-disulfonic acid in flow injection analysis. Dr. Sawada developed a highly sensitive Cu(I) detection system using e long flow cell. Dr. Sawada’s system can detect as little as 0-15 ppb Cu(I) in water samples without pretreatment.
