GEMINI surfactantS (M-S-M) ARE MADE UP OF TWO HYDROPHOBIC CHAINS AND TWO HYDROPHILIC HEADS CONNECTED THROUGH A SPACER[1]. THESE surfactantS HAVE DEMONSTRATED MANY UNIQUE PROPERTIES, SUCH AS LOWER CRITICAL MICELLE CONCENTRATION (CMC), GREATER EFFICIENCY IN LOWERING THE SURFACE TENSION OF WATER AND BETTER SOLUBILIZATION CAPABILITY COMPARED TO THE CONVENTIONAL surfactantS.THEY HAVE BEEN WIDELY USED IN THE FIELDS OF SOIL REMEDIATION, SEPARATION OF BIOMATERIALS, ENHANCED OIL RECOVERY AND DRUG ENTRAPMENT AND RELEASE[2-4]. IN THIS PAPER, THE PROPERTIES OF BINARY surfactant SYSTEMS OF GEMINI AND CONVENTIONAL surfactantS HAVE BEEN INVESTIGATED BY MEANS OF 3D LATTICE MONTE CARLO SIMULATION.

surfactantS ENTER WATERS AND WASTEWATERS MAINLY BY DISCHARGE OF AQUEOUS WASTES FROM HOUSEHOLD AND INDUSTRIAL LAUNDERING AND OTHER CLEANSING OPERATIONS [12]. THE SUBLATION METHOD IS SPECIFIC FOR surfactantS, BECAUSE ANY SUBSTANCE PREFERENTIALLY ADSORBED AT THE WATERGAS INTERFACE IS BY DEFINITION A surfactant. THE surfactant IS ADSORBED AT THE WATERGAS INTERFACES OF THE BUBBLES AND IS CARRIED INTO THE ETHYL ACETATE LAYER. THE SOLVENT IS SEPARATED, DEHYDRATED, AND EVAPORATED, LEAVING THE surfactant AS A RESIDUE SUITABLE FOR ANALYSIS. [34]. ...
