“…The U4f 7/2 binding energy for the uranyl compounds at the surface of the humic acid equals 382.6 ± 0.1 eV. This is in good agreement with the corresponding value of E b = 382.7 eV for UO 2 In the C1s spectrum of NHA one would expect a complicated structure since the carbon atoms are not chemically equivalent. The NHA A2 (Aldrich) has 4.8 meq/g carboxylic groups and 2.6 meq/g phenolic hydroxyl groups.…”

“…Five different types of reaction solutions were prepared by dissolving uranyl acetate (UO 2 (CH 3 COO) 2 Solid uranyl and iron humates were prepared by stirring deaerated NHA A2 (Aldrich) in an aqueous suspension with solutions 1 -5 for three days under nitrogen atmosphere. Table 1 gives the approximate ratios expressed in meq (mmol · ionic charge) of metal ion and humic acid carboxylic groups, which were chosen for the sample preparation.…”

“…tinide ion in the compound. Previously, we used XPS to determine the chemical state of uranium in samples containing reactor fuel from "lava" and compounds growing in it as a result of the accident at the fourth block of the Chernobyl nuclear power plant [2]. XPS was also used to study the interaction of the uranyl group with calcite and diabase [3], and humic acids [4] in aqueous solutions.…”
