Separation of Bovine Serum Albumin (BSA) Protein by Foam Fractionation Technique

Abstract

Foam fractionation is an effective, low-cost, and environmentally friendly method for water treatment that is widely applied to the removal of hazardous materials, organic materials, and metal ions from the wastewater by using the surfactant as a collector. This type of process known as the adsorption bubble separation technique. It uses bubbles as a separation medium and concentrates the surfactant from its aqueous solution by the difference of adsorption properties of the surfactant on gas–liquid interfaces. During the process of foam fractionation, it spared gas through the bottom of the column to create dispersed rising bubbles. They adsorbed the surfactant onto gas–liquid interfaces of the rising bubbles. We discuss here separate Bovine Serum Albumin from aqueous solution with haemoglobin by foam fraction method. To investigate the effect of the following variables on the enrichment ratio of total protein, the separation process like concentration of feed, the effect of pH, and the Effect of gas flow rate.
