Comment: |
original reaction equation given in the study was: »Fe-(OH)2 + UO2<2+> + CO3<2-> = (»Fe-O2)-UO2CO3<2-> + 2 H<1+>, This reaction represents two surface hydroxyls forming an edge-sharing bidentate surface complex with the uranyl ion. An exponent of two for the activity of »Fe-OH in the mass-action equation as suggested in [B02] is used.; IS was 0.001, 0.01 and 0.1 M NaCl |
