Iimveliso

Ukusetyenziswa kwe-silica capillary edibeneyo kwi-CE ngamanye amaxesha kunokuba yinto engathandekiyo ngenxa yemiphumo engathandekiyo kuquka i-adsorption yesampuli okanye ukungazinzi kwe-EOF.Oku kunokuphetshwa ngokugquma indawo yangaphakathi ye-capillary.Kulo msebenzi, sibonisa kwaye sibonisa iinoveli ezimbini ze-polyelectrolyte coatings (PECs) i-poly (2-(methacryloyloxy) ethyl trimethylammonium iodide) (PMOTAI) kunye ne-poly (3-methyl-1- (4-vinylbenzyl) -imidazolium chloride) (PIL- 1) ye-CE.Iicapillari ezigqunyiweyo zaphononongwa kusetyenziswa uthotho lwezithinteli ezinamanzi ezahlukahlukeneyo ze-pH, amandla e-ionic, kunye nokwakheka.Iziphumo zethu zibonisa ukuba i-polyelectrolytes ephandiweyo isetyenziswa njenge-semi-permanent (i-adsorbed physically adsorbed) i-coatings kunye ne-five runs stability ubuncinane phambi kokuba uhlaziyo olufutshane luyimfuneko.Zombini ii-PECs zibonise ukuzinza kwehle kakhulu kwi-pH 11.0.I-EOF ibiphezulu kusetyenziswa izithinteli ze-Good kune-sodium phosphate buffer kwi-pH efanayo kunye namandla e-ionic.Ubuninzi beengqimba ze-PEC ezifundwe yi-quartz cry stal microbalance yi-0.83 kunye ne-0.52 nm ye-PMOTAI kunye ne-PIL-1, ngokulandelanayo.I-hydrophobicity ye-PEC layers igqitywe ngokuhlalutya uchungechunge lwe-homologous ye-alkyl benzoates kwaye ibonakaliswe njengeendawo zokusabalalisa.Isiphumo sethu sibonisa ukuba zombini ii-PEC zine-hydrophobicity efaniswayo, eyenza ukuhlukana kwee-compounds kunye nelogi Po / w > 2. Ukukwazi ukwahlula izidakamizwa ze-cationic kuboniswe kunye ne-β-blockers, iikhompawundi zihlala zisetyenziswa kakubi kwi-doping.Zombini iingubo ziye zakwazi ukwahlula iimveliso ze-hydrolysis ze-ionic liquid 1,5-diazabicyclo [4.3.0] non-5-ene acetate kwiimeko ezine-acidic kakhulu, apho i-silica capillaries edibeneyo ayiphumelelanga ukuphumeza ukwahlukana.
