Abstract
The precipitation of calcite seed crystals has been investigated in synthetic sea water at 25°C. Over a range of supersaturation, 0.008–0.015, the precipitation reaction appears to be controlled by a surface process which, in contrast to a bulk diffusion reaction, is markedly inhibited by the presence of additives. The influence of a number of polyphosphonates on the rate of reaction has been investigated. The retardation effect of these additives has been attributed to the blocking of active sites by adsorption of phosphonate molecules at the crystal surface.
