Complexation of Paramagnetic Metal Ions by Aquatic Fulvic Acids

AbstractThe luminescence of aquatic humic substances in water is quenched over a broad range of pH by paramagnetic metal ions like iron(II) and manganese(II). The efficiency dependents on the pH of the solution and rises with increasing basicity; this parallels the complexing of metal ions by humic substances. No quenching of the luminescence is observed by the addition of aluminium(III).
