Impamyabumenyi yo Kugena Uburyo bwo Kugena Uburyo bwa Sodium Carboxymethyl Cellulose

Kugena urwego rwo gusimbuza (DS) ya sodium carboxymethyl selulose (CMC) ningirakamaro mugucunga ubuziranenge no kwemeza guhuza imiterere n'imikorere. Uburyo bwinshi burashobora gukoreshwa kugirango umenye DS ya CMC, hamwe na titre hamwe na tekinike ya spekitroscopique niyo ikoreshwa cyane. Dore ibisobanuro birambuye byuburyo bwo gutanga titre yo kumenya DS ya sodium CMC:

1. Ihame:

• Uburyo bwa titre bushingiye kumyitwarire hagati ya carboxymethyl mumatsinda ya CMC nigisubizo gisanzwe cyibanze, mubisanzwe hydroxide ya sodium (NaOH), mugihe cyagenwe.
• Amatsinda ya Carboxymethyl (-CH2-COOH) muri CMC yitwara hamwe na NaOH gukora sodium carboxylate (-CH2-COONa) namazi. Ingano yiyi reaction iragereranijwe numubare wamatsinda ya carboxymethyl aboneka muri molekile ya CMC.

2. Ibikoresho n'ibikoresho:

• Sodium hydroxide (NaOH) igisubizo gisanzwe cyo kwibandaho.
• Icyitegererezo cya CMC.
• Igipimo cya Acide-fatizo (urugero, phenolphthalein).
• Burette.
• Amashanyarazi.
• Amazi yamenetse.
• Stirrer cyangwa magnetic stirrer.
• Impirimbanyi zisesenguye.
• pH metero cyangwa impapuro zerekana.

3. Inzira:

1. Icyitegererezo:
   • Gupima umubare wihariye wa sample ya CMC ukoresheje impirimbanyi zisesenguye.
   • Gabanya icyitegererezo cya CMC mubunini buzwi bwamazi yatoboye kugirango utegure igisubizo cyibizwi. Menya neza kuvanga neza kugirango ubone igisubizo kimwe.
2. Umutwe:
   • Pipette ingano yapimwe yumuti wa CMC mumashanyarazi.
   • Ongeraho ibitonyanga bike byerekana aside-fatizo (urugero, phenolphthalein) kuri flask. Ibipimo bigomba guhindura ibara kumpera ya titre, mubisanzwe hafi ya pH 8.3-10.
   • Andika igisubizo cya CMC hamwe nigisubizo gisanzwe cya NaOH uhereye kuri burette hamwe no guhora. Andika ingano ya NaOH igisubizo wongeyeho.
   • Komeza titre kugeza aho iherezo rigeze, ryerekanwa no guhindura ibara rihoraho ryerekana.
3. Kubara:
   • Kubara DS ya CMC ukoresheje formula ikurikira:
   $��\; =\; �\; \times \; �\; \times \; �NaOH�CMC$

   DS = mCMC V × N × MNaOH

   Aho:

   • $��$

     DS = Impamyabumenyi yo gusimburwa.

   • $�$

     V = Umubare wa NaOH igisubizo cyakoreshejwe (muri litiro).

   • $�$

     N = Ubusanzwe igisubizo cya NaOH.

   • $�NaOH$

     MNaOH = Uburemere bwa molekuline ya NaOH (g / mol).

   • $�CMC$

     mCMC = Misa ya sample ya CMC yakoreshejwe (muri garama).

4. Ibisobanuro:
   • DS yabazwe yerekana impuzandengo yimibare ya carboxymethyl kumatsinda ya glucose muri molekile ya CMC.
   • Subiramo isesengura inshuro nyinshi hanyuma ubare impuzandengo ya DS kugirango umenye neza ibisubizo byizewe.

4. Ibitekerezo:

• Menya neza niba kalibibasi ikwiye yibikoresho hamwe nibisanzwe bya reagent kubisubizo nyabyo.
• Koresha igisubizo cya NaOH witonze kuko ari caustic kandi gishobora gutera umuriro.
• Kora titre mubihe byagenzuwe kugirango ugabanye amakosa nibihinduka.
• Emeza uburyo ukoresheje ibipimo ngenderwaho cyangwa isesengura rigereranya nubundi buryo bwemewe.

Ukurikije ubu buryo bwo gutanga titre, urwego rwo gusimbuza sodium carboxymethyl selulose (CMC) rushobora kugenwa neza, rutanga amakuru yingirakamaro yo kugenzura ubuziranenge no kugena inganda zitandukanye.
