抄録

Trace Cu²⁺ was detected with high selectivity using specific complexation with bathocuproinesulfonate (BCS) through flow-injection electrospray ionization mass spectrometry (FI-ESI-MS), which separates Cu²⁺ from coexisting metal ions by forming a Cu–BCS complex with a high mass number. Here, only [Cu^I(BCS)₂]³⁻ was obtained with a high ion count. Its calibration curve was linear from 1.0 × 10⁻⁸ to 1.0 × 10⁻⁵ M. This method was applied to determine the Cu-complexing capacities of humic acid solution and river water samples by adding traces of Cu²⁺.
