The kinetics of calcite dissolution in the presence of calcium chelating agents was investigated over the pH range of 3.3-12 using a rotating disk apparatus. The results show that the rate of dissolution is increased significantly by the presence of chelating agents such as CDTA, DTPA, and EDTA. The
The presence of suspended particles in solution causes an enhancement of the mass transport to a rotating disc electrode, the magnitude of which is dependent on the volume fraction of the particulate material. By monitoring the transport limited current due to the reduction/oxidation of a suitable e
## Abstract The kinetics of dissolution have been expressed using a generalized dissolution rate equation which combines concentration driving force and area terms and thus enables large amounts of undersaturation to be used in experiments.
