Obrazcy byli sobrany w gorah Malakanda, KPK, i izmel'cheny do melkih chastic. Obrazcy byli äxtragirowany cherez apparat Soxleta razlichnymi rastworitelqmi dlq udaleniq rastworimyh äxtraktiwnyh i woskowyh weschestw. Syraq cellüloza obrabatywalas' w awtoklawe schelochnymi weschestwami dlq razrusheniq swqzej. Bol'shinstwo polqrnyh weschestw byli udaleny s pomosch'ü JeDTA i perekisi wodoroda. Krome togo, obrazcy byli ochischeny s pomosch'ü uxusnoj kisloty i rastwora azotnoj kisloty. Cellüloza byla nejtralizowana dwojnoj distillirowannoj wodoj do polucheniq nejtral'nogo rN. Ochischennaq cellüloza byla oharakterizowana s pomosch'ü razlichnyh analiticheskih metodow, takih kak rentgenowskaq difrakciq (XRD) pokazala wysokuü kristallichnost' 73%. FTIR pokazywaet udalenie razlichnyh funkcional'nyh grupp s powerhnosti. TGA pokazywaet, chto cellüloza, poluchennaq iz razlichnyh istochnikow drewesiny, pokazala, chto poterq wody proishodit pri 100¿C, rastworimyh äxtraktow pri 250¿C, a lignina i gemicellülozy pri 350¿C. SEM pokazywaet, chto morfologiq i forma powerhnosti imeüt horosho zametnye pory. Vydelennaq cellüloza obladaet wysokoj kristallichnost'ü, termicheskoj stabil'nost'ü i horoshimi mehanicheskimi swojstwami.
