A yield of 25.9% was obtained. This indicates that ethanol effectively extracted the soluble components. The theoretical total soluble content of the solid is unknown, but the residue’s pale color suggests most chlorophyll was removed.
The fundamental principle relies on mass transfer and solubility. The solvent penetrates the solid matrix, dissolves the solute, and the resulting solution diffuses out of the solid. The driving force for this transfer is the concentration gradient between the solid phase and the liquid phase. solid-liquid extraction
The next time you brew a cup of coffee or apply a natural skincare product, take a moment to appreciate the elegant science of solid-liquid extraction at work. A yield of 25
)—compressed past their critical temperature and pressure points. The fundamental principle relies on mass transfer and
The liquid solvent contacts the solid particle. It must penetrate the pore network of the insoluble matrix to reach the trapped solute. 2. Dissolution of Solute
