dulmar:

NH2 (amino) waa tiir soo saarista aminopropyl oo leh jel silica. Waxay leedahay heerka daciifka ah ee joogtada ah ee dabaysha iyo beddelka anion, iyada oo loo marayo is-weydaarsiga daciifka ah ee anion (xalka aqueous) ama xayeysiinta polarity (xalka dabiiciga ah ee aan polar) si loo gaaro saameynta, sidaas darteed waxay leedahay door dual ah. Marka la diyaariyo xalalka aan polarka ahayn, sida n-hexane, waxay samayn kartaa curaarta hydrogen oo leh molecules leh -oh, -nh ama -sh, iyo amino PKa= 9.8; Saamaynta anion way ka daciifsan tahay kan SAX, iyo PH < 7.8 xal aqueous, waxaa loo isticmaali karaa sida wakiilka daciif ah anion beddelka, kaas oo loo isticmaali karaa in laga saaro anions xoog leh sida sulfonic acid ee muunad.
Bondka aminopropyl waa adsorbent xoog leh ee xalalka organic nonpolar iyo waxa uu leeyahay sii hayn daciif ah anion- sarrifka ee xal aqueous.NH2 si fiican u qabataa noocyo kala duwan oo muunado substrates oo loo isticmaali karaa in cuntada, deegaanka, daawooyinka iyo daawada.
