Mu rwego rwa chimie, bimwe mu bintu by’umwimerere, bitewe n’imiterere yabyo yo kudashonga cyangwa gushonga gato mu mazi, bitera ingorane nyinshi mu mikoreshereze ifatika. Ariko, iyo ibyo bintu by’umwimerere bibana n’ibintu by’ingenzi, gushonga kwabyo biriyongera cyane, ikintu kizwi nka gushonga. Ibintu by’ingenzi bikora nk’ibintu bishonga muri ubu buryo, mu gihe ibintu by’umwimerere bikora nk’ibintu bishonga byitwa gushonga. Iyi nkuru izasuzuma uburyo bwo gushonga n’ibintu biyigiraho ingaruka.
Kubaho kw'ingufu zishonga bifitanye isano rya hafi n'imiterere y'ibintu bitanga ubushyuhe. Ubushakashatsi bwagaragaje ko iyo ingano y'ibintu bitanga ubushyuhe iri hasi ugereranyije n'ingano y'ibintu bitanga ubushyuhe (CMC), ubushobozi bwo gushonga bw'ibintu bikomoka ku bimera ntibuhinduka cyane; icyakora, iyo ingano irenze CMC, ubushobozi bwo gushonga buriyongera cyane. Ibi biterwa nuko kuri ubu buryo, ibintu bitanga ubushyuhe bitangira gukora micelles, kandi gushonga bifitanye isano rya hafi no kuremwa kwa micelles.
Bitewe n'aho ikintu cyashongeshejwe kiri muri micelle, hari uburyo bune bw'ingenzi bwo gushongesha:
①Gushonga imbere muri micelle: Ubu buryo bukwiriye ibintu byoroshye bya hydrocarbon bitari polar, nka benzene, ethylbenzene, na n-heptane. Bishobora gushonga byoroshye imbere muri micelle kuko imbere muri micelle hashobora gufatwa nk'ikintu cyuzuye cya hydrocarbon, gifite imiterere isa n'iyi.
②Gushonga mu gice cya micelle palisade: Ku bintu by’umwimerere nka alkoholi na aside bizunguruka, bikwirakwizwa mu buryo butandukanye kandi bujyanye n’uturemangingo twa surfactant. Ibice bitari polar bikorana n’amatsinda ya surfactant adafite hydrophobic binyuze mu mbaraga za van der Waals, mu gihe ibice bya polar bihujwe n’amatsinda ya surfactant adafite hydrophilic binyuze mu mbaraga za van der Waals n’imigozi ya hydrogen.
③Gushonga ku buso bwa micelle: Ibintu binini, amarangi, nibindi, bizashyirwa ku buso bwa micelle kandi bigashyirwaho binyuze mu mbaraga za van der Waals cyangwa hydrogen bonds, bityo bikongera gushonga kwabyo mu mazi. Ariko, ingano y'ishonga hakoreshejwe ubu buryo ni ntoya.
④Gushonga hagati y’iminyururu ya polyoxyethylene: Ku bintu bifasha mu gushonga nk’ibinyabutabire byo mu bwoko bwa polyoxyethylene, bitewe n’uruhererekane rurerure rw’igice cyabyo gihumeka amazi, akenshi biba biri mu mimerere yo kwizinga. Ibintu by’ibinyabuzima bishobora gupfunyikwa imbere no gufatirwa n’iminyururu ya polyoxyethylene ihumeka amazi. Ubu buryo bufite ingano nini y’ishonga.
Ubu buryo bune bwo gushonga bukurikiza ihame rya 'like dissolves like', kandi uburyo bwo gushonga kuva kuri nini kugeza kuri nto ni: gushonga hagati y'iminyururu ya polyoxyethylene > gushonga mu gice cya micelle palisade > gushonga imbere muri micelle > gushonga ku buso bwa micelle.
Ni ngombwa kumenya ko nubwo gushonga kw'ibintu bikomoka ku bimera mu mazi byiyongera bitewe no gushonga, imiterere y'umuti ntabwo ihinduka cyane. Ibi biterwa nuko molekile zikomoka ku bimera zishobora gukora uduce duto, bigatuma umubare w'uduce mu muti udakomeza kwiyongera cyane. Ibi kandi bigaragaza mu buryo butaziguye ingaruka zo gufatana no guhuza kwa micelles ku mubare munini wa molekile zikomoka ku bimera.
2. Ibintu bigira ingaruka ku gushonga kw'amazi
Gushonga kw'ibintu bidafite ishingiro ntibifitanye isano ya hafi no kuba hari micelles gusa, ahubwo binagira ingaruka ku miterere y'ikintu gishonga n'ikintu gishonga. Byongeye kandi, ikintu icyo ari cyo cyose gishobora kugira ingaruka kuri CMC y'ibintu bitanga ishingiro kizagira ingaruka no ku gushonga kw'ibintu bidafite ishingiro.
Umushongi (umushongi w'ibintu bishongesha)
Ubwinshi bw'ibinure: Uko surfactant iba nyinshi, ni ko micelles ziba nyinshi kandi ni ko micelles zihurira, bigatuma zishobora gukorana n'ibinure byinshi bishonga.
Imiterere ya molekile: Uko uruhererekane rwa hydrocarbon rurerure rukora, niko ingaruka zo gushonga zirushaho gukomera; ku bintu bikoresha amashanyarazi bifite itsinda rimwe rikunda hydrophilic, niko uruhererekane rwa hydrocarbon rukora hydrophobic rurushaho kuba rurerure, niko CMC yabyo iba nto kandi ingaruka zo gushonga zirushaho gukomera. Byongeye kandi, ingaruka zo gushonga za surfactants zitari ionic zikunze kuba zikomeye kurusha iz’ibintu bikoresha amashanyarazi.
Gushonga
Muri rusange, uko ibintu bishonga bishonga birushaho kuba byinshi, ni ko ubushobozi bwo gushonga buba bwinshi. Ibi bishobora guterwa n'uko ibintu bishonga bishonga mu gice cy'isi biba bishobora gukorana n'amatsinda akunda gushonga ku buso bwa micelles binyuze mu migozi ya hydrogen na van der Waals. Muri icyo gihe, ibice byabyo bitari mu gice cy'isi bikunda gukorana n'amatsinda akunda gushonga ku gice cy'isi.
Ubushyuhe
Ku bintu bikoresha ionic surfactants, kwiyongera k'ubushyuhe byongera ingaruka zabyo zo gushonga. Ibi biterwa nuko kwiyongera k'ubushyuhe byongera CMC, bigatuma ibintu byinshi bikoresha ionic surfactants bishobora gushonga mu gisubizo bigatuma habaho micelles nyinshi.
Ku bintu bidafite ionic bya polyoxyethylene, ubushobozi bwo gushonga nabwo buriyongera uko ubushyuhe bwiyongera. Ariko, iyo ubushyuhe bugeze cyangwa bukarenga aho igicu giherereye, ingaruka zo gushonga ziragabanuka.
Electrolyte
Kongeramo electrolyte bishobora kongera ubushobozi bwo gushonga bwa surfactants za ionic kuri hydrocarbons ariko bikagabanya ubushobozi bwazo bwo gushonga kuri polar. Ibi biterwa nuko electrolytes zigabanya igice cy'amashanyarazi y'amatsinda ya hydrophilic, bigatuma imiterere y'amatsinda ya hydrophilic ku buso bwa micelle iba nto, ibyo bikaba bitanoze gushyiramo polar solubilizates.
Ku bintu bidafite ionic surfactants, kongeramo electrolytes bishobora kongera ubushobozi bwabyo bwo gushonga. Ibi biterwa n'ingaruka zo gushyira umunyu mu kirere, bigabanya uburyo amazi ahagarara ku bintu binini bidafite ionic, byongera ubwikorezi bwabyo, kandi bigatuma micelles zikora neza.
Gushonga mu buryo bw'ingufu ni ikintu kigoye giterwa n'ibintu bitandukanye. Mu gusobanukirwa neza ibi bintu n'uburyo bikorana, dushobora gukoresha neza uburyo bwo gushonga mu kunoza imikorere y'ibinyabutabire n'imikorere y'ibicuruzwa.
