帮我润色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 latif

Romruen et al. (2022) conducted delignification treatments on four agricultural waste materials: 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 cellulose extracted from corn cob still contained trace amounts of lignin and hemicellulose. El Amri et al. (2023) used the reed plant Typha latifolia as a raw material and performed dewaxing treatment with a mixture of acetone and ethanol, followed by further treatment using NaOH and hydrogen peroxide (H2O2) solutions to obtain cellulose. FTIR results indicated that the alkaline treatment removed most of the lignin and hemicellulose from the raw material. Sun et al. (2021) used continuous alkaline treatment on a cellulose-rich matrix, resulting in a 9.3% increase in crystallinity and a 45.3% decrease in yield. However, FTIR results showed that extracted cellulose still contained residual lignin. Therefore, although alkaline treatment is a cost-effective method for cellulose extraction, its drawback lies in the low purity of the extracted cellulose.
