• Izinyibilikiswa: I-Ebano -dinee (E-E-E-E-E-E-E-E-E-E-E-E-E-E-E-E-E-E-EDE) okanye amanzi ase-Deoried (amanzi).
2. Ukuhamba kwenkqubo
Inyathelo 1
o I-hisve inyibilikisi (hayi) ₂ kunye ne-na₂teo₃ kwi-1: 1 ralar ralar kwinyibilikisi phantsi kwesinyibilikisi.
Inyathelo 2: Ukuncitshiswa kwempendulo
o Yongeza iarhente yokunciphisa (umzekelo, i-n₂hi₄) kunye netywina kwi-Autoclave ephezulu ye-Autoclave.
Iimeko zokuphendula:
 Ubushushu: 180-20 ° C
 Ixesha: 12-24 iiyure
 Ingcinezelo: Ukuzenzela (i-3-5 MPA)
o Ukuphendula i-Equation: ++ ITeo32- + ukunciphisa iarhente
Inyathelo lesi-3: Unyango lweposi
O I-Centrifuyiifuyimbo yokukhetha imveliso, hlamba izihlandlo ezingama-3-5 nge-ethanol kunye namanzi.
o Yomile phantsi kwe-vacuum (i-60-80 ° C kwiiyure ezingama-4-6).
3. Iiparamitha eziphambili
• I-Precursor I-STRICROR: 0.1-9.5 mol / l
• Ulawulo lwe-PH: 9-11 (iimeko ze-alkaline zithanda ukuphendula)
• Ulawulo lwe-Paunticle Ulawulo: Lungisa uhlobo ngohlobo lweSolvent (umzekelo, uEva uvelisa i-nanowisi; isigaba se-acerateus sivelise i-nanopalicals).
