Nhanganyaya kune Surfactants
Masurfactants ane amphiphilic molecular structure: imwe mugumo ine hydrophilic boka, inonzi hydrophilic musoro, nepo imwe magumo ine hydrophobic boka, rinozivikanwa se hydrophobic muswe. Musoro we hydrophilic unobvumira ma surfactants kunyungudika mumvura mune yavo monomer fomu.
Iro hydrophilic boka rinowanzova boka repolar, iro rinogona kuva boka re carboxyl (-COOH), boka re sulfonic acid (-SO3H), boka reamino (-NH2), amines uye salts yavo, mapoka e-hydroxyl (-OH), mapoka e-amide, kana ether linkages (-O-) semimwe mienzaniso yepolar hydrophilic mapoka.
Iro hydrophobic boka rinowanzo risiri-polar hydrocarbon cheni, senge hydrophobic alkyl cheni (R- yealkyl) kana mapoka anonhuhwirira (Ar- for aryl).
Masurfactants anogona kuiswa mune ionic surfactants (kusanganisira cationic uye anionic surfactants), asiri-ionic surfactants, amphoteric surfactants, akasanganiswa surfactants, nevamwe. Mune surfactant solutions, kana iko surfactant yasvika pane imwe kukosha, surfactant mamorekuru anoumba akasiyana akarongerwa aggregates anozivikanwa semicelles. Maitiro ekuita micellization, kana micelle kuumbwa, chinhu chakakosha chakakosha chemhinduro dze surfactant, sezvo zvakawanda zvakakosha zviitiko zvemukati zvine chekuita nekuumbwa kwemamicelles.
Iko kusungirirwa uko ma surfactants anoumba micelles mumhinduro inodaidzwa seCritical Micelle Concentration (CMC). Micelles haina kugadzika, spherical zvimiro; asi, vanoratidza kusarongeka kwakanyanya uye kuchinja kwechimiro. Mune mamwe mamiriro ezvinhu, ma surfactants anogona kuratidza reverse micelle states.
Zvinhu Zvinokonzera CMC:
- Chimiro che surfactant
- Mhando uye kuvapo kwezvinowedzera
- Tembiricha
Kudyidzana Pakati peSurfactants uye Mapuroteni
Mapuroteni ane asiri-polar, polar, uye anochaja mapoka, uye akawanda amphiphilic mamorekuru anogona kudyidzana nemapuroteni nenzira dzakasiyana. Zvichienderana nemamiriro ezvinhu, ma surfactants anogona kugadzira ma molecular aggregates ane zvimiro zvakasiyana, senge micelles kana reverse micelles, ayo anodyidzana zvakasiyana nemapuroteni.
Kudyidzana pakati pemapuroteni uye ma surfactants (Protein-Surfactant, PS) inonyanya kusanganisira kupindirana kwemagetsi uye kupindirana kwehydrophobic. Ionic surfactants inopindirana nemapuroteni kunyanya kuburikidza nemagetsi emagetsi eboka repolar uye kupindirana kwehydrophobic yealiphatic carbon chain, inosunga kune polar uye hydrophobic nzvimbo dzeprotein, nokudaro kugadzira PS complexes.
Non-ionic surfactants inonyanya kupindirana nemapuroteni kuburikidza nemasimba e-hydrophobic, apo maketani e-hydrophobic anopindirana nematunhu e-hydrophobic emapuroteni. Iko kudyidzana kunogona kukanganisa zvese chimiro uye basa reiyo surfactant uye protein. Naizvozvo, rudzi uye kuungana kwevanoshandisa surfactants, pamwe chete nemamiriro ekunze, zvinotarisa kuti ma surfactants anodzikamisa here kana kukanganisa mapuroteni, pamwe nekuti anokurudzira kuunganidzwa kana kupararira.
HLB Kukosha Kwema Surfactants
Kuti surfactant iratidze basa rayo rakasiyana-siyana, inofanirwa kuenzanisa iyo hydrophobic uye hydrophilic zvikamu. Iyo HLB (Hydrophile-Lipophile Balance) chiyero cheiyo hydrophilic-lipophilic chiyero cheva surfactants uye inoshanda sechiratidzo che surfactants' hydrophilic uye hydrophobic properties.
Iko kukosha kweHLB kukosha kwehukama (kubva pa0 kusvika pa40). Semuenzaniso, parafini ine HLB inokosha ye0 (hapana hydrophilic component), polyethylene glycol ine HLB inokosha ye20, uye yakanyanya hydrophilic SDS (sodium dodecyl sulfate) ine HLB inokosha ye 40. HLB inokosha inogona kushanda semutungamiri kana uchisarudza surfactants. HLB yepamusoro inoratidza hydrophilicity iri nani, nepo HLB yakaderera ichiratidzira kushomeka kwehydrophilicity.
