Characteristics of Interfacial Layer on Reverse Micelles.

Abstract

The characteristics of monolayer on reverse micelles are described focusing on the solubilization of solute molecules and the dynamics of solute exchanges between two reverse micelles and between a reverse micelle and a flat interface. It is demonstarted that the characteristics can be controlled by surfactant and solvent species used and the electrolyte concentration in aqueous bulk phase coexinsting with reverse micelles. Key words : reverse micelles / phase diagram / solute solubilization / dynamics of solute exchanges 1.•@ ‚Í ‚ ¶ ‚ß ‚É ‚ ‚éŽí ‚Ì ŠE-ÊŠˆ•ÊŠˆ•« •Ü ‚Í,-L ‹@-n "} ' † ‚Å,•Å •-Ê ‚Ì •…‚Ì ' ¶ •Ý‚Ì ‰º‚Å Ž© "-"I ‚ɋÕW‚µ,‹t ƒ~ƒZƒ‹ ‚AE OEÄ ‚Î ‚ê ‚é ‹Ã•W'Ì ‚ð OE`•¬ ‚· ‚é.‚± ‚Ì ‹t ƒ~ƒZƒ‹ ‚Í ‚³ ‚ç ‚É '½ ‚-‚Ì •…‚ð Žae‚è•ž ‚ñ ‚Å-c •• ‚µ,•× ‚© ‚-•ª Š" ‚³ ‚ê ‚½ •…ƒv •[ ƒ‹ ‚Ì ŽüˆÍŽüˆÍ ‚ð ŠE-ÊŠˆ•ÊŠˆ•« •Ü•ª Žq ‚Ì •e •…Šî ‚ª Žae ‚è ˆÍ ‚Ý,'a •…Šî ‚Í-L ‹@-n "} 'Š ‚É OEü‚¢ ‚½•\ '¢ ‚ð ‚AE‚Á‚Ä, ‹Ã•W'Ì ‚Í "M-ÍŠw"I ‚ɈÀ'è ‚É ‚È ‚‚Ă¢ ‚é.‚± ‚Ì •ó 'Ô ‚ðHoar‚AESchulman1)‚Í ƒ} ƒCƒNƒ• ƒGƒ} ƒ‹ ƒVƒ ‡ƒ" ‚AE OEÄ ‚ñ ‚¾.‹t ƒ~ƒZƒ‹ ‚AEƒ} ƒCƒNƒ• ƒGƒ} ƒ‹ ƒVƒ ‡ƒ" ‚AE‚Ì-¾ Šm‚È ‹ae•Ê ‚Í ‚È ‚³ ‚ê ‚È ‚¢ ‚± ‚AE‚ª '½ ‚-,‚± ‚± ‚Å ‚Í •…‚ð Žae‚è•ž ‚ñ ‚¾•ó 'Ô ‚É ‚ ‚é-L ‹@-n "} ' † ‚Ì ‹Ã •W'Ì ‚ð ‹t ƒ~ ƒZƒ‹ ‚AE‚µ ‚Ĉµ ‚¤.-L ‹@-n "} ' † ‚Ì •ª Š" ‚³ ‚ê ‚½•…ƒv •[ ƒ‹ ‚â ‚» ‚Ì Žü ‚è ‚Ì ŠE-ÊŠˆ•ÊŠˆ•« •Ü'P •ª Žq'w‚Í •¨ Ž¿•ª-£ "½‰ž,ƒG ƒl ƒ‹ ƒM•[ •Ï Š· ‚È ‚Ç‚Ì "ÁˆÙ ‚È•ê ‚AE‚µ ‚Ä-p ‚¢ ‚é ‚± ‚AE‚ª ‚Å ‚« ‚é.‚± ‚Ì ‚½‚ß,‹t ƒ~ƒZƒ‹ ‚Ì ‚AE‚é ‹" "®‚É ‚‚¢ ‚Ä,Šî 'b "I ŠÏ "_ ‚© ‚ç•L "Í ‚ÈOE¤‹ † ‚ª ‚È ‚³ ‚ê ‚Ä ‚« ‚½2•`4).‹t ƒ~ƒZƒ‹ ‚É ‚Í •…‚ð Žû-e‚Å ‚« ‚é OEÀ ŠE‚ª ‚ ‚Á‚Ä,•… ‚È‚¢ ‚µ•…-n ‰t‚ð '½-Ê "Y‰Á ‚· ‚é ‚AE,ƒ~ ƒZƒ‹ ‚Í •…‚ð Žó ‚¯ •t ‚¯ ‚È ‚-‚È ‚Á‚Ä,‰ß •è ‚Ì •…-n ‰t‚ð‹t ƒ~ƒZƒ‹ 'Š ‚© ‚ç•ú •o ‚· ‚é.‚± ‚Ì OE‹‰Ê,ƒ~ ƒZ ƒ‹ 'Š ‚AE •…-n‰t'Š ‚Ì2'Š OEn ‚ª "¾ ‚ç ‚ê ‚é.-{ "Á•W‚Å‚Í,•¨ Ž¿•ª-£ ‚â •y 'f ‚È ‚Ç‚Ì "½‰ž‚ð'Î •Û ‚AE‚µ ‚Ä‚¢ ‚é ‚ª,ƒ~ ƒZƒ‹ ‚Ö‚Ì •¨ Ž¿ ‚Ì •o "ü ‚ð ‚± ‚Ì ‰ß •è ‚È•…-n ‰t'Š ‚ð‰î‚µ ‚Ä•i •s ‚³ ‚¹ ‚é ‚± ‚AE ‚ª '½ ‚¢.‚± ‚Ì2'Š OEn‚É‚¨‚¯OEn‚É‚¨‚¯ ‚é ‹t ƒ~ƒZƒ‹ ‚Å‚Í,ŠE-ÊŠˆ •« •Ü•ª Žq ‚Ì ƒ~ƒZƒ‹ •\-Ê ‚É‚¨‚¯‚É‚¨‚¯ ‚é "z ˆÊ •[ "U•ó 'Ô ‚Í ‚¢ ‚í ‚ä ‚é Ž© 'R ‚Ì •ó 'Ô(ŠE-ÊŠˆ•ÊŠˆ•« •Ü 'P •ª Žq'w ‚Ì 'e •« ƒG ƒl ƒ‹ ƒM•[ ‚ª ŽÀŽ¿•ã ƒ[ ƒ• ‚É ‚È ‚é•ó 'Ô)‚É ‹ß ‚-‚È ‚é ‚Ì ‚ª "Á'¥ ‚Å ‚ ‚é5).‚± ‚Ì •ó 'Ô ‚Å‚Í,•¡ ŽG‚È ‹t ƒ~ƒZƒ‹ 'Š ‚Ì ‚AE‚é ‹" "®‚ª ‚· ‚± ‚µŠÈ'P ‰»‚³ ‚ê ‚é.‚± ‚± ‚Å ‚Í, Žå ‚AE‚µ‚Ä ‚± ‚Ì2'Š OEn‚Ì •ó 'Ô ‚É ‚¨‚¯‚¨‚¯ ‚é ‹t ƒ~ƒZƒ‹ ‚Ì ‚AE ‚é‹" "®‚ð,'˜ ŽÒ‚Ì OE¤‹ † ‚ð ‚Ü ‚ ¶ ‚¦ ‚Ä•l ˆÄ‚· ‚é.‚AE ‚
