Abstract:
Calcium oxalate, having a lower solubility product than CaCO3, precipitates on the surface of host carbonate crystals in the presence of oxalate ions. This blocks the carbonate crystals from further interaction, and the process stops when the surface of the mineral grains is fully covered with Ca-oxalate. A kinetic rate equation allows detailed interpretation of the experimental results obtained by this interaction process. This equation, which has been developed in this work, can be used to determine the specific surface area of the carbonate mineral. © 1984 The Williams & Wilkins Co.
