title: Interaction energies in the coagulation of calcium oxalate monohydrate.
abstract: In the present work, Gregory's approximation was used to calculate the Hamaker constant (A131) for the van der Waals interactions between calcium oxalate monohydrate (COM) particles in water. An average value of 1.135 (+/- 0.341) x 10(-20) J for A131 was calculated for COM particles at 37 degrees C in aqueous solutions. Theoretical calculations predicting coagulation behavior based on the calculated A131 are consistent with experimental data.
