Ibicuruzwa

Gukoresha silika capillary yambaye ubusa muri CE birashobora rimwe na rimwe kutoroha kubera ingaruka zitifuzwa zirimo adsorption yicyitegererezo cyangwa ihungabana rya EOF.Ibi birashobora kwirindwa akenshi gutwikira imbere imbere ya capillary.Muri iki gikorwa, turerekana kandi turanga ibice bibiri bishya bya polyelectrolyte (PECs) poly (2- (methacryloyloxy) ethyl trimethylammonium iyode) (PMOTAI) na poly (3-methyl-1- (4-vinylbenzyl) -imidazolium chloride) (PIL- 1) muri CE.Capillaries yometseho yakozwe hifashishijwe urukurikirane rwamazi yo mumazi atandukanye pH, imbaraga za ionic, hamwe nibigize.Ibisubizo byacu byerekana ko iperereza ryakozwe na polyelectrolytes rishobora gukoreshwa nkigice cyahoraho (cyerekanwe kumubiri) gifite byibuze bitanu bitwara neza mbere yuko hakenerwa kuvugurura igihe gito.PEC zombi zerekanye ko byagabanutse cyane kuri pH 11.0.EOF yari hejuru ikoresheje buffer nziza kuruta hamwe na sodium ya fosifate ya sodium kuri pH imwe nimbaraga za ionic.Ubunini bwibice bya PEC byizwe na quartz cry stal microbalance yari 0.83 na 0.52 nm kuri PMOTAI na PIL-1.Hydrophobicity yinzego za PEC yagenwe nisesengura ryuruhererekane rwa homologique ya alkyl benzoates kandi bigaragazwa nkibikwirakwizwa.Ibisubizo byacu byerekana ko PEC zombi zifite hydrophobicity igereranywa, yatumaga gutandukanya ibice hamwe na log Po / w> 2. Ubushobozi bwo gutandukanya imiti ya cationic bwerekanwe hamwe na β-blokers, ibice byakoreshejwe nabi muri doping.Ipitingi zombi zanashoboye gutandukanya hydrolysis yibicuruzwa byamazi ya ionic 1.5-diazabicyclo [4.3.0] acetate itari 5-ene mubihe bya acide cyane, aho capillaries ya silika yambaye ubusa yananiwe kugera kubitandukanya
