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.
