NOVELTY - Producing a colloidal aphron/graphene hybrid fluid composition involves forming a first mixture by mixing a graphene derivative solution and a biopolymer solution in a volume ratio in a range of (1:0.45)-(1:0.9) (graphene derivative solution: biopolymer solution). The second mixture is formed by mixing the first mixture with at least one of an ionic-surfactant solution and a non-ionic surfactant solution in a volume ratio in a range of (1:0.023)-(1:0.068) (first mixture: ionic-surfactant solution) if mixed with an ionic-surfactant solution and in a volume ratio in a range of (1:0.023)-(1:0.068) (first mixture: non-ionic surfactant solution) if mixed with a non-ionic surfactant solution. USE - Method for producing a colloidal aphron/graphene hybrid fluid composition that is used in field of biotechnology, separation industry, membranes, and smart-fluid technology. ADVANTAGE - The CGAs are dynamically structured systems which are continuously transforming due to bubble breakage, coalescence, and disproportionation. The method for producing a stable CGA with high surface area and active sites, narrow size distribution. The CGAs have high interfacial area and relatively high stability which make them good candidates for different applications. High interfacial area per unit volume enables CGAs to absorb molecules for separation applications. Furthermore, CGAs are able to withstand a pressure up to 200 bar which is about ten times higher than the pressure which conventional bubbles can endure.
