  • Title: Modeling of protein and phenolic compound removal from aqueous solutions by electrocoagulation.
    Author: Robić G, Miranda EA.
    Journal: Biotechnol Prog; 2010; 26(1):186-91. PubMed ID: 19918881.
    Abstract:
    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 such as plant pigments and sugars. Simple and time-dependent models were developed based on the complex formation between these biological substances and the aluminium hydroxide gel phase. The models developed represent a good agreement with experimental data (R(2) as high as 0.992). Besides construction of the models, the effect of pH on the efficiency of removal of proteins and phenolic compounds was evaluated. It was found that this parameter has significant effect on the efficiency of the electrocoagulation and the maximal removal efficiency for bovine serum albumin and phenolic compound catechin was observed at pH 8.0.
