Ligands acetate

Cu(ll) complexes with carboxylate ligands (acetate, malonate, oxalate) undergo photodecarboxylation during irradiation within their LMCT bands, for example (231) ... 

The predicted waste inventory for the repository indicates that potentially significant quantities of the organic ligands—acetate, citrate, oxalate, and EDTA—will be present (US DOE, 1996). Actinide interactions with these compounds were not considered in the speciation and solubility modeling, as calculations suggested that they would be mostly complexed by transition metal ions (Fe, Ni " ", Cr, and Mn " ") released by corrosion of the steel waste containers and waste components. A thermodynamic model of actinide-ligand interactions appropriate to brines will be included in solubility calculations for WIPP recertification. 

In an another stndy related to the additivity rule (Alessi and Fein 2010), the sorption of Cd(II) in mixtures of kaolinite. Bacillus subtilis bacterial cells, and iron oxy-hydroxide (HFO) was performed in the absence and presence of an organic ligand, acetate. The resnlts indicate that for systems containing B. subtilis, HFO, and kaolinite, the component additivity approach is a reasonable predictor of metal distribution, with the accuracy limited by the accuracy of the stability constants of the important surface complexes. However, in systems including acetate, the additivity rule predictions significantly nnderestimate the extent of adsorption above pH 5, likely due to the formation of ternary Cd-acetate surface complexes on each surface.
