The Influence of Oxyanions on the EDTA-Promoted Dissolution of Goethite
Organic ligands, such as EDTA, accelerate the dissolution of silicate and oxide minerals. In natural systems oxyanions can compete with organic ligands for mineral surface sites thereby affecting ligand-promoted dissolution rates. Oxyanions can either enhance or inhibit dissolution depending upon …

The tolerance of a Rhodococcus drinking water isolate and Zoogloea ramigera to silver nanoparticles in biofilm and planktonic cultures
… from Ag NPs in chloride environments via ligand-promoted dissolution. Further work is needed to examine the antibacterial mechanism of Ag NPs against planktonic and biofilm cells to better understand how the release of nanoparticles into the environment can affect microorganisms in natural …

Forsterite Dissolution Kinetics: Applications and Implications for Chemical Weathering
… important factors that affect silicate mineral dissolution rates and grain lifetimes in the weathering environment. I determined an empirical rate law for forsterite dissolution of forsterite in oxalic acid solutions: based on a series of 124 semi-batch reactor experiments over a pH range of 0 …
