Diffusion studies in extraction

[speedycaster]

Hi guys, I have a question regarding ways to investigate diffusion.

Here's the case, I have a fruit which is used for solvent (eg methanol) extraction to extract active compounds from the fruit. Now I have to do a sub-study to study the diffusion of these active compounds from the fruit to the solvent.

My idea is based on Fick's law which relates diffusion to pressure difference, surface area and thickness of the membrane. In order to study the diffusion kinetics, what are the ways i could use to approach this matter?

*Personal thought: Use various sizes of of the fruit pieces for the experiment and plot the graph based on the extracted content.

One way to investigate diffusion is to use a diffusion cell. A diffusion cell consists of two compartments separated by a membrane. One compartment contains the fruit and the other contains the solvent. The membrane will allow the active compounds to diffuse from the fruit into the solvent. You can measure the concentration of the active compounds in both compartments at different time intervals and plot the data on a graph to determine the rate of diffusion. You can also vary the size of the fruit pieces to observe the effect on the diffusion rate. Additionally, you can vary the thickness of the membrane to observe its effect on the diffusion rate.

One way to investigate diffusion is by using a dialysis membrane. This membrane is semi-permeable, allowing some molecules to pass through while blocking others. You can place the fruit and the solvent on either side of the membrane and measure the concentrations of the active compounds before and after the diffusion process. This will give you an idea of how much of the compounds diffuse over time and how they are affected by the thickness of the membrane. Additionally, you can vary the concentration of the solvents on either side of the membrane to observe how this affects the diffusion rate. Another way to investigate diffusion is to use a diffusion cell. In this experiment, you place the fruit and the solvent in separate compartments of a cell and measure the concentration of the active compounds before and after the diffusion process. By varying the surface area and thickness of the cell walls, you can observe how these factors affect the rate of diffusion. You can also investigate diffusion by performing a batch experiment. In this experiment, you place the fruit and the solvent in a container and measure the concentration of the active compounds over time. By varying the amount of fruit and the concentration of the solvent, you can observe how these factors affect the rate of diffusion. Finally, you can also investigate diffusion by performing a kinetic study. In this experiment, you measure the rate at which the active compounds diffuse from the fruit to the solvent over time. By varying the temperature, pressure, and surface area of the fruit, you can observe how these factors affect the rate of diffusion.
