Fluorescence measurements of metal ions in drinking water employing complex forming organic magnets result in signals depending linearly on the metal ion concentration range. In this paper we present and analyze measurements with and without additives with potential influence on the complexation. We found that sulfite addition to neocuproine does not sensitize the fluorescence. Moreover we found that neocuproine can be used as an efficient masking agent for spurious copper in the analysis of nickel with Newport Green.
