Abstract
Initial dissolution rates at 25°C and pH ~ 4 for all samples varied with spinning speed and ranged from 1-3 μmol mâ2 sâ1 for laminar flow conditions to almost 3-6 μmol mâ2 sâ1 as the transition to turbulence began. At lower temperatures, the rate was lower, and increasing spinning velocity had less effect. The strongest spinning rate dependence occurred far from equilibrium, and it became a less important factor as the saturation state increased.
