| Abstract: | Limestone-based material can reduce concentrations of cadmium below 0.001 mg/L (1 ppb) in water, resulting in > 99% removal efficiency. Thermodynamic constraints appear to be favorable for reactions involving the formation of otavite during cadmium removal. Thermodynamic values for these reactions yield a theoretical removal limit of 0.0015 mg/L or better for cadmium, in reasonable agreement with tests on laboratory and field samples that show cadmium removal at levels less than 0.001 mg/L. |
