The　maximum　bubble　pressure　technique　has　been　used　to　study　the　adsorption　kinetics　of　binary　mixtures　of　an　anionic　Gemini　surfactant　C9pPHCNa　with　a　cationic　conventional　surfactant　C10TABr　in　aqueous　solutions.　The　dynamic　surface　tension　data　were　analyzed　using　the　revised　Ward　and　Tordai　equations　as　well　as　the　micelle　dissociation　kinetic　model　suggested　by　Joos　et　al.　The　apparent　diffusion　coefficient　Da　below　the　cmc,　the　adsorption　barrier　εa　and　the　micelle　dissociation　constant　kmic　were　obtained.　The　Das　at　short　times　and　at　long　times　were　respectively　0.2　-　16　×　1010　and　0.08　-　0.9　×　1010　 　m2　s-1,　the　latter　corresponded　to　the　adsorption　barrier　εa　of　10-20　kJ　mol-1.　The　minimum　εa　appeared　at　the　mole　fraction　of　C9pPHCNa　(　α1,　on　a　surfactant-only　basis)　in　the　bulk　solution　being　0.33.　The　kmics　of　the　mixed　micelles　were　about　16-2300　s-1.　The　most　stable　mixed　micelles　were　formed　at　α1　=　0.2　rather　than　at　α1　=　0.33　owing　to　great　discrepancy　of　hydrophobicity　between　the　two　components.　These　results　indicated　that　the　composition　of　mixed　solution　was　an　important　factor　affecting　the　adsorption　kinetics　and　the　micelle　stability.　©　2005　Elsevier　Inc.　All　rights　reserved.
