description

Koksnes hidrolītiskā oksidēšana nanocelulozes iegūšanai. Krecers K., zinātniskie vadītāji Vīksna A., Fiļipova I. Maģistra darbs, 48 lappuses, 19 attēli, 14 tabulas, 57 literatūras avoti, 5 pielikumi. Latviešu valodā. Darbā ir veikta apšu hibrīdu un priedes hidrolītiska oksidēšana izmantojot amonija persulfāta šķīdumu dažādos koncentrāciju, laika un temperatūru apstākļos. Iegūtiem paraugiem noteica ekstrakvielu daudzumu, izmantojot paātrinātā šķīdinātāja ekstrakciju lignīna, pelnu un celulozes daudzumu un mitrumu. Paraugi tika analizēti ar infrasarkanās spektrometrijas, gāzu hromatogrāfijas un skenējošās mikroskopijas metodēm, tika noteikta kristalizācijas pakāpe izmantojot rentgendifraktometriju. KOKSNE, NANOCELULOZE, LIGNĪNS, CELULOZE, PAĀTRINĀTĀ ŠĶĪDINĀTĀJA EKSTRAKCIJA, INFRASARKANĀ SPEKTROMETRIJA.
