Electrocoagulation of quinone pigments.

Dechlorophyllation by electrocoagulation.

Electrocoagulation was used for dechlorophyllation of alcoholic extracts from five plants. The results showed that for every plant extract studied, electrocoagulation was more efficient than the classical solvent extraction method in removing plant pigments, while not affecting the important secondary metabolites in those extracts.

Solvent effects in electrocoagulation of selected plant pigments and tannin.

Electrocoagulation of a plant extract and certain substances representative of selected classes of plant pigments, viz. chlorophyll, a carotenoid, a phenolic substance and a tannin, was performed in ethanol containing varying amounts of water (15-75%). The results showed that the extent and efficiency of coagulation of these substances tends to vary in a manner directly related to the water con...

Modeling of protein and phenolic compound removal from aqueous solutions by electrocoagulation.

Electrocoagulation is a technique basically applied in water and wastewater treatment, but which has a number of potential applications in polymer, protein, drug, and vaccine delivery. In this work, we correlate the current applied between the electrodes to the removal of phenolic compounds or protein from aqueous solutions, but the principle can also be applied to other biological compounds su...
