Amorphous silica dissolution kinetics in freshwater environments: Effects of Fe2+ and other solution compositional controls
| Description: | This dataset contains results of laboratory batch experiments in the Ecohydrology Research Group in Waterloo, Ontario. The goal of the research was to study the rates of amorphous silica dissolution as a function of solution chemical composition. The dataset includes time series chemical concentration data of dissolved silicon concentrations in the dissolution batch experiment systems for different batch system treatments representing different solution chemical compositions. Specifically, the solution composition effects studied were: pH, ferrous iron (Fe(II) concentration and salinity. These time series concentration data were used to calculate dissolution rate constants. |
