The surface area, pore volume and pore diameter were increased at lower volume of solvent, whereas they decreased by increasing the volume of solvent.
Drug release was partial with recovery to complete dependent on type and volume of solvent.
They reported that the positive effect of volume of solvent on oil yield was as a result of increase in the concentration driving force as volume of solvent increases.
This is important for the subsequent radiolabeling step which uses only a small volume of solvent (0.5 mL).
Under the optimum conditions, chlorobenzene was used as eluent to diminish the volume of solvent remarkably.
For convenience-sake, a 2-mL volume of solvent, ideal for GC MS automatic injection, was used in the S3DE experiments.
The effect of various process variables such as temperature, time, volume of solvent, particle size, and their interaction on oil yield was investigated.
One row received the same volume of solvent (96% EtOH) as introduced with the fungal extracts, while another row received deion.
It was found that oil yield increased with increase in temperature, time and volume of solvent but decreased with increase in seed particle size.
In 1983, Bicchi et al. [23] made improvements to the microapparatus to decrease the volume of solvent used to 100 μL and to avoid hot organic solvent reflux.
Factorial design was applied to determine the influence of temperature, volume of solvent and extraction time on the efficiency of the extraction of total chlorins.
