Alaabta

Isticmaalka koofiyadaha silica ee fudayd qaawan ee CE ayaa mararka qaarkood noqon kara mid aan fiicneyn sababtoo ah saameyn aan loo baahnayn oo ay ku jiraan xajinta saamiga ama xasilloonida EOF.Tan inta badan waa laga fogaan karaa iyadoo la dahaadhaa dusha gudaha ee xididka.Shaqadan, waxaan ku soo bandhigeynaa oo aan ku muujineynaa laba nooc oo cusub oo polyelectrolyte ah (PECs) poly (2- (methacryloyloxy) ethyl trimethylammonium iodide) (PMOTAI) iyo poly (3-methyl-1- (4-vinylbenzyl) -imidazolium chloride) (PIL- 1) CE.Xididdada dahaarka leh ayaa la dersay iyadoo la isticmaalayo taxane biyo xidheeno ah oo kala duwan pH, xoogga ionic, iyo ka kooban.Natiijooyinkayagu waxay muujinayaan in polyelectrolytes-ka la baaray ay yihiin kuwo loo isticmaali karo sidii semi-joogta ah (jir ahaan la isku dhejiyay) daahan oo leh ugu yaraan shan socodsiiso xasilloonida ka hor dib u soo kabashada dahaarka gaaban lagama maarmaanka ah.Labada PEC waxay muujiyeen xasillooni aad hoos ugu dhacday pH 11.0.EOF-ku wuu ka sarreeyaa iyadoo la isticmaalayo kaydiyeyaasha Wanaagsan marka loo eego soodhiyam fosfooraska buffer ee isla pH iyo xoogga ionic.Dhumucda lakabyada PEC ee uu bartay quartz cry stal microbalance waxay ahayd 0.83 iyo 0.52 nm PMOTAI iyo PIL-1, siday u kala horreeyaan.Hydrophobicity ee lakabyada PEC waxaa lagu go'aamiyay falanqaynta isku-dhafan ee alkyl benzoates oo loo muujiyay sida joogtaynta qaybinta.Natiijadeenu waxay muujinaysaa in labada PEC ay lahaayeen hydrophobicity barbardhig ah, taas oo awood u leh kala soocida xeryahooda log Po/w> 2. Awoodda kala saarista daawooyinka cationic waxaa lagu muujiyay β-blockers, xeryahooda inta badan si khaldan loo isticmaalo doping.Labada dahaarba waxay sidoo kale awoodeen inay kala soocaan alaabada hydrolysis ee dareeraha ionic 1,5-diazabicyclo [4.3.0] non-5-ene acetate ee xaaladaha acidic aadka u sarreeya, halkaas oo daboolka silica ee qaawan ay ku guuldareysteen inay dhammaystiraan kala-soocidda.
