Rolandi for the explanation of solubility equilibrium models and M.
This is especially important as the solubility equilibriums are complex in these systems and therefore present an important microbiological contribution.
(2003) performed a solubility equilibrium experiment of soils in presence of Ca[Cl.sub.2] solution and equilibrated the suspensions for 2h.
(2003) also suggested that solubility equilibrium experiments could be grouped by soils into those with low pH in which Fe- or Al-phosphates control P solubility.
It can be seen that the filled polymers absorb more gas when the polymer samples reach the solubility equilibrium
. However, the time required for the gas absorption to reach equilibrium (for the pressure curve to become flat) is not affected by fillers.
Other features different from those carried out with the spherical polymer are: a) oxetane polymer to solvent ratio is much higher so that the solubility equilibrium is reached before all the polymer is dissolved, b) agitation is achieved by placing the transparent vessel in a shaker apparatus, in which the resulting hydrodynamics are different from those with the spherical oxetane polymer, where a magnetic stirrer was used.
The assumption of solubility equilibrium at the solid/liquid interface was validated by comparing the equilibrium solubility parameters obtained from the model on the basis of best fit with the experimental equilibrium solubility values where the difference was found to be at most 1%.
