Optimization.an. Characterization.of Cellulose Extraction.from Grev.llea robusta (Silky Oak) Leav.s by Soda-An.hraquin.n. Pulpin. Usin. Respon.e Surface methodology

引用

Green.an. Sustain.ble Chemistry 2024年第3期14卷 43-65页

作者： Catherin. n. muya John.m. On.ari Lydia W. n.en.a Joab O. On.an.o Wilson.m. Gitari Departmen. of Chemistry The University of Nairobi Nairobi Kenya School of Chemical an. material Scien.e The Technical University of Kenya Nairobi Kenya

Respon.e surface methodology (RSm) usin. the cen.ral composite design.(CCD) was applied to examin. the impact of soda-an.hraquin.n. pulpin. con.ition. on.Grev.llea robusta fall leav.s. The pulpin. factors studied were: n.OH charge 5% to 20% w/v. pulpin. time 30 to 180 min.tes, an. the an.hraquin.n. charge 0.1 to 0.5% w/w based on.the ov.n.dried leav.s. The respon.es ev.luated were the pulp yield, cellulose con.en., an. the degree of delign.fication. v.rious regression.models were used to ev.luate the effects of v.ryin. the pulpin. con.ition.. The optimum con.ition. attain.d were;n.OH charge of 14.63%, 0.1% an.hraquin.n., an. a pulpin. period of 154 min.tes, correspon.in. to 20.68% pulp yield, 80.56% cellulose con.en., an. 70.34% lign.n.remov.l. An.lysis of v.rian.e (An.v.), was used to determin. the most importan. v.riables that improv. the extraction.process of cellulose. The experimen. outcomes matched those predicted by the model (Predicted R2 = 0.9980, Adjusted R2 = 0.9994), demon.tratin. the adequacy of the model used. FTIR an.lysis con.irmed the elimin.tion.of the n.n.cellulosic fiber con.tituen.s. The lign.n.an. hemicellulose-related ban.s (aroun. 1514 cm−1, 1604 cm−1, 1239 cm−1, an. 1734 cm−1) decreased with chemical treatmen., in.icatin. effectiv. cellulose extraction.by the soda-an.hraquin.n. method. Similar results were obtain.d by XRD, SEm an. thermograv.metric an.lysis of the extracted cellulose. Therefore, Grev.llea robusta fall leav.s are suitable ren.wable, cost-effectiv., an. en.0}ron.en.ally frien.ly n.n.wood biomass for cellulose extraction.
