Silver Chloride Precipitation-limiting Factor for Accurate Silver Determination in Ag-accumulating Mushrooms After Nitric Acid Digestion.

ABSTRACT: Wild-growing mushrooms (macromycetes, macrofungi) are capable of accumulating high amounts of trace elements, including noble metals. In a series of analytical experiments, this study focused on the problem of correct determination of Ag mass fractions in the biomass of Ag-accumulating mushrooms, Ag-hyperaccumulators in particular. A unique experimental setup enabled to compare Ag determination in selected mushroom samples first by the non-destructive neutron activation analysis (INAA) utilizing ¹¹⁰Ag isotope, second by the high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS) after HNO₃ hotplate and microwave digestions. Furthermore, Ag-spiking experiments were conducted with three mushroom species containing 860, 6200, and 21,000 mg Cl kg^-1</
