帮我润色以及精简以下段落使其符合科研论文的逻辑注意不要改变意思：Romruen等 Romruen et al 2022对四种农业废弃物：稻草、玉米芯、菠萝叶和菠萝皮进行脱蜡处理后用亚氯酸钠NaClO2溶液和氢氧化钾KOH溶液提取纤维素。傅立叶红外光谱结果表明从玉米芯中提取的纤维素仍然含有微量的木质素和半纤维素。El Ameri等 El Amri et al 2023以芦苇植物大叶香蒲Typha l

Romruen et al. (2022) conducted delignification of four types of agricultural waste, namely rice straw, corn cob, pineapple leaves, and pineapple peel, followed by extraction of cellulose using sodium chlorite (NaClO2) and potassium hydroxide (KOH) solutions. Fourier transform infrared spectroscopy (FTIR) results showed that the extracted cellulose from corn cob still contained traces of lignin and hemicellulose. El Amri et al. (2023) used the reed plant Typha latifolia as a raw material and delignified it using a mixed solution of acetone and ethanol. Cellulose was then extracted by treating it with NaOH and hydrogen peroxide (H2O2) solutions. FTIR results showed that the alkaline treatment removed most of the lignin and hemicellulose present in the raw material. Sun et al. (2021) employed continuous alkaline treatment to increase the crystallinity of cellulose in a fiber-rich substrate by 9.3%, but the yield decreased by 45.3%. However, FTIR results revealed the presence of lignin residues in the extracted cellulose. Therefore, although alkaline treatment is a cost-effective method for cellulose extraction, its drawback is the low purity of the extracted cellulose.
