| Popis: | A novel microtiter plate array for the quantification and identification of metal ions in drinking water was compared to human taste panel analysis. The array is based on nonspecific interactions between analyte metal ions and lanthanide chelates with non-antenna and antenna ligands, leading to a luminescence signal profile unique to sample components. The performance of the method was demonstrated in the detection of Cu2+ and Fe2+ ions in active coal filtered and nonfiltered household water. The sensitivity and objectiveness was compared to human taste panel analysis. Detection limits of |
