where dc/dt is the rate of dissolution velocity, D is the diffusion coefficient, A is the surface area of the solid, C s is the concentration of the solid in the diffusion layer surrounding the solid, and C x is the concentration of the solid in the bulk dissolution medium.
All the identified process variables influenced the particle size and dissolution velocity of aceclofenac.
As known, the electrolyte temperature determines the velocity of oxidation and chemical dissolution, the surface porosity, as well as mechanical stress at the metal/oxide interface in the process of electrochemical anodization [11 13].
Based on Noyes-Whitney equation [30], the dissolution velocity of particles increases due to surface area enlargement as described in Equation 1: Open image in new window Figure 6 Distance of diffusion layer in microparticles and nanoparticles.
As velocities increase, unsaturated water moves deep into the bedrock, and the rate of dissolution is greatly increased.
The hematocrit might also influence the displayed clotting time by the velocity of the blood streaming into the reaction zone of the test strip, or the rate of dissolution of the dried reagents in the blood, or the concentration of reagent dissolved in the blood.
Studies of dissolution rates vary widely.
There is a sense of unwinding, of subsiding, of dissolution.
Volume of dissolution media changed.
Lack of dissolution information (e.g., missing information on dissolution media volume, individual dissolution data, multimedia dissolution, etc).
