Adsorpsi Surfaktan Nonionik Alkil Poliglikosida pada Antarmuka Fluida-Fluida

Abstract: Nonionic  surfactants  have  been  used  extensively  in  various  industrial  applications  such  as cleaning,  personal  care,  crop  protection,  paint  and  coating,  textile  finishing,  emulsion stabilization,  food  and  leather  processing.  In  this  study,  we  have  studied  the  adsorption  of three  nonionic  surfactants  of  alkyl  polyglycoside,  namely  commercial  APG  from  Cognis  and APG  produced  from  glucose  as  well  as  APG  synthesized  from  sago  starch,  at  fluid–fluid interfaces. The variation of surface and interfacial tension with the concentration of surfactant in  the  bulk  was  studied,  and  the  data  were  fitted  using  a  surface  equation  of  state  derived from the Langmuir isotherm. The agreement between (c) data and Langmuir isotherm model was very good.
Keywords: adsorption, air/water interface, interfacial tension, surface tension
